As a promising technique, OFDM has been widely used in emerging broadband communication systems, such as digital audio broadcasting (DAB), high-definition television (HDTV), and 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 require 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 amongst others, clipping, clipping-and-filtering (CF), coding, companding transform, active constellation extension (ACE), selected mapping (SLM), and partial transmit sequence (PTS). This book proposes an improvement in the selected mapping technique. The resulting scheme can also be applied to the multiple transmitting antenna cases. Further, it compares the simulation results to the existing techniques namely exponential companding transform, repeated clipping and filtering, and adaptive active constellation extension.

An authoritative survey of different contexts, methodologies, and theories of applied communication The field of Applied Communication Research (ACR) has made substantial progress over the past five decades in studying communication problems, and in making contributions to help solve them. Changes in society, human relationships, climate and the environment, and digital media have presented myriad contexts in which to apply communication theory. The Handbook of Applied Communication Research addresses a wide array of contemporary communication issues, their research implications in various contexts, and the challenges and opportunities for using communication to manage problems. This innovative work brings together the diverse perspectives of a team of notable international scholars from across disciplines. The Handbook of Applied Communication Research includes discussion and analysis spread across two comprehensive volumes. Volume one introduces ACR, explores what is possible in the field, and examines theoretical perspectives, organizational communication, risk and crisis communication, and media, data, design, and technology. The second volume focuses on real-world communication topics such as health and education communication, legal, ethical, and policy issues, and volunteerism, social justice, and communication activism. Each chapter addresses a specific issue or concern, and discusses the choices faced by participants in the communication process. This important contribution to communication research: Explores how various communication contexts are best approached Addresses balancing scientific findings with social and cultural issues Discusses how and to what extent media can mitigate the effects of adverse events Features original findings from ongoing research programs and original communication models and frameworks Presents the best available research and insights on where current research and best practices should move in the future A major addition to the body of knowledge in the field, The Handbook of Applied Communication Research is an invaluable work for advanced undergraduate students, graduate students, and scholars.
Comparative research has gained enormous popularity in communication and media studies in the last two decades and is increasingly conducted in international research teams. Collaboration with scholars from different countries brings many advantages, but it is also prone to conflict. Sophia Charlotte Volk presents the first systematic reflection on the conceptual, methodological, and social challenges of international collaborative and comparative studies in communication science. A systematic review of comparative studies and expert interviews with communication scholars shed light on how challenges manifest themselves empirically and what solutions have proven to be appropriate. The book proposes a phase model of collaborative and comparative research that can serve as a guide for scholars on what conditions should be created for productive collaboration in temporary research projects.
Thoroughly revised and updated, this third edition integrates perspectives from the social sciences and the humanities, focusing on methodology as a strategic level of analysis that joins practical applications with theoretical issues. The Handbook comprises three main elements: historical accounts of the development of key concepts and research traditions; systematic reviews of media organizations, discourses, and users, as well as of the wider social and cultural contexts of communication; and practical guidelines with sample studies, taking readers through the different stages of a research process and reflecting on the social uses and consequences of research. Updates to this edition include: An overview of the interrelations between networked, mass, and interpersonal communication. A new chapter on digital methods. Three chapters illustrating different varieties of media and communication research, including industry–academic collaboration and participatory action research. Presentation and discussion of public issues such as surveillance and the reconfiguration of local and global media institutions. This book is an invaluable reference work for students and researchers in the fields of media, communication, and cultural studies.
Building on the measures included in the original 1994 volume and subsequent 2009 volume, Communication Research Measures III: A Sourcebook extends its coverage of measurement issues and trends across the entire communication discipline. Volume III features entirely new content and offers an assessment of new measures in mass, interpersonal, instructional, group, organizational, family, health, and intercultural communication and highlights work in emergent subdisciplines in communication, including social media and new communication technologies, sports communication, and public relations. The “best of the best” from 2009 through today, the profiled research measures in Volume III serve as models for future scale development and constitute the main tools that researchers can use for self-administered measurement of people’s attitudes, conceptions of themselves, and perceptions of others. This book is ideal for undergraduate and graduate courses that emphasize quantitative research methods, measurement, and/or survey design across communication studies disciplines.
By using a wide diversity of theoretical and methodological approaches and by encompassing both cross-national and longitudinal analyses, this volume sheds new light on comparative political communication research, such as personalization, globalization, democratization, and the changing nature of journalism,
This book is a collection of accepted papers that were presented at the International Conference on Communication and Computing Systems (ICCCS-2016), Dronacharya College of Engineering, Gurgaon, September 9–11, 2016. The purpose of the conference was to provide a platform for interaction between scientists from industry, academia and other areas of society to discuss the current advancements in the field of communication and computing systems. The papers submitted to the proceedings were peer-reviewed by 2-3 expert referees. This volume contains 5 main subject areas: 1. Signal and Image Processing, 2. Communication & Computer Networks, 3. Soft Computing, Intelligent System, Machine Vision and Artificial Neural Network, 4. VLSI & Embedded System, 5. Software Engineering and Emerging Technologies.
