Master's Thesis from the year 2012 in the subject Engineering - Communication Technology, grade: none, , course: M.Tech, language: English, abstract: As a promising technique, OFDM has been widely used in emerging broadband communication systems, such as digital audio broadcasting (DAB), high-definition television (HDTV), wireless local area network (IEEE 802.11a and HIPERLAN/2). However, as the OFDM signals are the sum of signals with random amplitude and phase, they are likely to have large PAPR that requires a linear high-power- amplifier (HPA) with an extremely high dynamic range, which is expensive and inefficient. Furthermore, any amplifier nonlinearity causes intermodulation products resulting in unwanted out-of-band power. A number of approaches have been proposed to deal with the PAPR problem, including clipping, clipping-and-filtering (CF), coding, companding transform, active constellation extension (ACE), selected mapping (SLM), partial transmit sequence (PTS), and so on. This thesis proposes an improvement in Selected Mapping technique and Simulation results are compared to existing techniques namely Exponential Companding Transform, Repeated Clipping and Filtering and Adaptive Active Constellation Extension. The improvements which are proposed in classical Selective Mapping technique satisfies the PAPR Reduction criteria with reducing the computational complexity. Also this new scheme has an important advantage of avoiding the extra bits along with the trans...

A fully comprehensive reference combining digital communications and RFIC (Radio Frequency Integrated Circuits) in one complete volume There are many books which focus on the physical implementation of the RF/analog part of transceivers, such as the CMOS design, or the signal processing involved in digital communications. However, there is little material dedicated to transceiver architecture and system design. Similarly, much of the existing literature looks at concepts useful for dimensioning, yet offers little practical information on how to proceed for dimensioning a line-up from scratch, and on the reasons for proceeding that way. This book redresses the balance by explaining the architecture of transceivers and their dimensioning from the perspective of a RFIC architect from within industry. It bridges the gap between digital communication systems and radiofrequency integrated circuit design, covering wireless transceiver architecture and system design from both system level and circuit designer aspects. • Covers digital communication theory, electromagnetism theory and wireless networks organization, from theories to implementation, for deriving the minimum set of constraints to be fulfilled by transceivers • Details the limitations in the physical implementation of transceivers to be considered for their dimensioning, in terms of noise, nonlinearity, and RF impairments • Presents transceiver architecture and system design in terms of transceivers budgets, transceivers architectures, and algorithms for transceivers

Most executives and business students are familiar with how the rule-based system functions; few understand how relation-based system works (which accounts for the majority of the countries in the world). Many dismiss it as backwards and attribute it to cultural traditions and norms (such as the Chinese guanxi tradition). This book dispels these myths and shows that people rely on the relation-based system not owing to specific cultural factors, but because of the stage of development in these countries. When the market is limited in scale and informal networks are thick, the relation-based system can be quite effective and efficient. The author applies this line of thinking to explain why business practices differ and how business people should interact across the two governance systems.

This book explains Wireless Sensor Networks energy constraints of battery-powered sensor nodes necessitate energy-efficient communication. The major existing solutions are based on classical layered protocols approach, which leads to significant overhead. It is much more efficient to have a unified scheme which blends common protocol layer functionalities into a cross-layer module. In this paper, a efficient crosslayer protocol (XLP) is introduced, which achieves congestion control, data fragmentation, routing, and medium access control in a cross-layer fashion. Our approach combines medium access organization with routing. in a cross-layer simulation platform, the state-of-the- art layered and cross-layer protocols have been implemented along with XLP for performance evaluations. XLP significantly improves the communication performance and outperforms the traditional layered protocol architectures in terms of both network performance and implementation complexity.

A guide to strategic communication that can be applied across a range of subfields at all three levels—grand strategic, strategic, and tactical communication Communication is a core function of every human organization so when you work with communication you are working with the very core of the organization. Written for students, academics, and professionals, Strategic Communication Theory and Practice: The Cocreational Model argues for a single unified field of strategic communication based in the three large core subfields of public relations, marketing communication, and health communication, as well as strategic communicators working in many other subfields such as political communication, issues management, crisis communication, risk communication, environmental and science communication, social movements, counter terrorism communication, public diplomacy, public safety and disaster management, and others. Strategic Communication Theory and Practice is built around a cocreational model that shifts the focus from organizational needs and the messages crafted to achieve them, to a publics-centered view placing publics and their ability to cocreate new meanings squarely in the center of strategic communication theory and practice. The author—a noted expert in the field—outlines the theories, campaign strategies, common issues, and cutting edge challenges facing strategic communication, including the role of social media, ethics, and intercultural strategic communication. As the author explains, the term «strategic communication» properly refers only to the planned campaigns that grow out of research and understanding what publics think and want. This vital resource answers the questions of whether, and how, strategic-level skills can be used across fields, as it: Explores the role of theory and the cocreational meta-theory in strategic communication Outlines ethical practices and problems in the field Includes information on basic campaign strategies Offers the most recent information on risk communication, preparedness and terrorism communication, and employment in strategic communication Redefines major concepts, such as publics, from a cocreational perspective

The reduction principle is a common idea which states that while researching the stability of solutions of the dynamic system (the system of differential, difference, differential-difference equations) the order of the researched system can be decreased. As the main obstacle in researching a dynamic system is a big dimension of the system, decreasing the order significantly simplifies the stability of the research process.This work contains some ways of decreasing the system order. The author aimed to keep the details to a minimum, to facilitate a better understanding of the main ideas, and the rigor of explanations is replaced by examples and references to the original works.The project Modern Mathematics for Engineers is addressed to upper-course University students in Mathematics specialties, to graduate students and to researchers who apply Mathematics in different spheres.

Diploma Thesis from the year 2001 in the subject Electrotechnology, grade: 1,7, University of Ulm, 34 entries in the bibliography, language: English, abstract: In today's world, there are mainly two types of communication networks: circuitswitched networks and packet-switched networks. The current telephone networks are mostly based on the circuit-switched networks, whereas the Internet is mainly based on the packetswitched networks, which are also called IP networks. However, there is a strong tendency to combine both of these networks, which points to the direction that the IP networks are going to replace services provided by current telephone networks. This would eventually mean that IP networks might replace the telephone networks, in the future.Following are some reasons why IP networks seem to replace the circuit-switchednetworks:· First of all, the IP networks provide cheaper communication. Considering thatthe Internet access is nearly free, the cost advantage of IP networks gets clearer[25].· Secondly, IP networks provide the ability of integrating the data and voiceapplications, and even some other applications, like video-conferencing,integrated voice mail, e-mail, and the like [26].· Another important reason is that IP networks allow open implementation ofend systems.

A comprehensive reference giving a thorough explanation of propagation mechanisms, channel characteristics results, measurement approaches and the modelling of channels Thoroughly covering channel characteristics and parameters, this book provides the knowledge needed to design various wireless systems, such as cellular communication systems, RFID and ad hoc wireless communication systems. It gives a detailed introduction to aspects of channels before presenting the novel estimation and modelling techniques which can be used to achieve accurate models. To systematically guide readers through the topic, the book is organised in three distinct parts. The first part covers the fundamentals of the characterization of propagation channels, including the conventional single-input single-output (SISO) propagation channel characterization as well as its extension to multiple-input multiple-output (MIMO) cases. Part two focuses on channel measurements and channel data post-processing. Wideband channel measurements are introduced, including the equipment, technology and advantages and disadvantages of different data acquisition schemes. The channel parameter estimation methods are then presented, which include conventional spectral-based estimation, the specular-path-model based high-resolution method, and the newly derived power spectrum estimation methods. Measurement results are used to compare the performance of the different estimation methods. The third part gives a complete introduction to different modelling approaches. Among them, both scattering theoretical channel modelling and measurement-based channel modelling approaches are detailed. This part also approaches how to utilize these two modelling approaches to investigate wireless channels for conventional cellular systems and some new emerging communication systems. This three-part approach means the book caters for the requirements of the audiences at different levels, including readers needing introductory knowledge, engineers who are looking for more advanced understanding, and expert researchers in wireless system design as a reference. Presents technical explanations, illustrated with examples of the theory in practice Discusses results applied to 4G communication systems and other emerging communication systems, such as relay, CoMP, and vehicle-to-vehicle rapid time-variant channels Can be used as comprehensive tutorial for students or a complete reference for engineers in industry Includes selected illustrations in color Program downloads available for readers Companion website with program downloads for readers and presentation slides and solution manual for instructors Essential reading for Graduate students and researchers interested in the characteristics of propagation channel, or who work in areas related to physical layer architectures, air interfaces, navigation, and wireless sensing
