Digital communications techniques have been continuously developed and re?ned for the past ?fty years to the point where today they form the heart of a multi-hundred billion dollar per year industry employing hundreds of thousands of people on a worldwide basis. There is a continuing need for transmission and reception of digital signals at higher and higher data rates. There are a variety of physical limits that place an upper limit on these data rates, and so the question naturally arises: are there alternative communi- tion techniques that can overcome some of these limitations? Most digital communications today is carried out using electronic devices that are essentially “linear,” and linear system theory has been used to c- tinually re?ne their performance. In many cases, inherently nonlinear devices are linearized in order to achieve a certain level of linear system performance.

Digital Communications with Chaos Excerpt :

Since the 1970's, there has been a great deal of research effort spent on studying chaotic systems and the properties of the chaotic signals generated. Characterized by their wideband, impulse-like autocorrelation and low cross-correlation properties, chaotic signals are useful spread-spectrum signals for carrying digital information. Spectrum spreading has become one of the most popular modulation techniques for high-speed wireless communications. It makes use of signals of very wide bandwidth to carry information at relatively low data rates, and possesses advantages such as low probability of interception, resistance to jamming, multiple-access capability and mitigation to multipath effect, which are particularly important in a wireless scenario. In addition to enjoying the aforementioned benefits, chaotic signals can be generated using simple circuitries, thus lowering the cost of transceivers. Early study of chaos-based communication systems was focused on a single-user case. In the past few years, more effort has been put on investigating systems with multiple-access capability, which is a key feature of spread-spectrum communication systems. Digital Communications with Chaos presents a detailed study of some multiple-access schemes used for chaos-based communications, and evaluates their performance. In addition, the effectiveness of the multiuser detection techniques, whose primary objective is to reduce interference between users and hence improve performance, is evaluated in the context of multiple-access digital communication systems. Hot research topic Describes communication technologies for the future Authors among the pioneers researching in chaos-based communications

Chaotic Signals in Digital Communications Excerpt :

Chaotic Signals in Digital Communications combines fundamental background knowledge with state-of-the-art methods for using chaotic signals and systems in digital communications. The book builds a bridge between theoretical works and practical implementation to help researchers attain consistent performance in realistic environments. It shows the possible shortcomings of the chaos-based communication systems proposed in the literature, particularly when they are subjected to non-ideal conditions. It also presents a toolbox of techniques for researchers working to actually implement such systems. A Combination of Tutorials and In-Depth, Cutting-Edge Research Featuring contributions by active leading researchers, the book begins with an introduction to communication theory, dynamical systems, and chaotic communications suitable for those new to the field. This lays a solid foundation for the more applied chapters that follow. A Toolbox of Techniques—Including New Ways to Tackle Channel Imperfections The book covers typical chaos communication methods, namely chaotic masking, chaotic modulation, chaotic shift key, and symbolic message bearing, as well as bidirectional communication and secure communication. It also presents novel methodologies to deal with communication channel imperfections. These tackle band-limited channel chaos communication, radio channels with fading, and the resistance of a special chaotic signal to multipath propagations. In addition, the book addresses topics related to engineering applications, such as optical communications, chaotic matched filters and circuit implementations, and microwave frequency-modulated differential chaos shift keying (FM-DCSK) systems. Insights for Both Theoretical and Experimental Researchers Combining theory and practice, this book offers a unique perspective on chaotic communication in the context of non-ideal conditions. Written for theoretical and experimental researchers, it tackles the practical issues faced

Chaotic Electronics in Telecommunications Excerpt :

At the code level, discrete-time chaotic systems can be used to generate spreading codes for DS-SS systems. At the signal level, continuous-time chaotic systems can be used to generate wideband carriers for digital modulation schemes. The potential of chaos engineering is now recognized worldwide, with research groups actively pursuing the exploitation of chaotic phenomena in cryptography, spread spectrum communications, electromagnetic interference reduction, and many other applications. Although some noteworthy results have already been achieved, until now, the field has lacked both a systematic treatment of these developments and a careful, quantitative comparison of chaos-based and conventional techniques. Chaotic Electronics in Telecommunications fills both of those needs. It addresses the use of chaos in digital communications applications, from the coding level to circuit design. Each chapter offers a formal exposition of the theoretical and engineering tools needed to apply chaos, followed by discussion of the algorithms and circuits needed to apply the theory to real-world communications systems.

Digital Communications 1 Excerpt :

The communication chain is constituted by a source and a recipient, separated by a transmission channel which may represent a portion of cable, an optical fiber, a radio channel, or a satellite link. Whatever the channel, the processing blocks implemented in the communication chain have the same foundation. This book aims to itemize. In this first volume, after having presented the base of the information theory, we will study the source coding techniques with and without loss. Then we analyze the correcting codes for block errors, convutional and concatenated used in current systems.

Embracing Chaos Excerpt :

Embracing Chaos is about the different crises during the last decade: the financial crisis, the identity crisis, the migration crisis, the Brexit crisis, the COVID19 crisis and the climate crisis. We live on the edge, from crisis to crisis, and one of the main things we can do is become more resilient and respect our planet. The book is about that new normal and leadership. It offers a valuable view of the challenges for the European Union to become a real federation - the United States of Europe - and for the West in general in defending liberal democracy. The volume describes how populism is being driven by the increase in the social divide and rising inequality and why the West needs to protect its values from propaganda from Russia & China and illiberal democracies. Fascinating in the book is the idea of creating a new Union of the West between Europe and North America.

Streamline your organization's communication with the powerful and easy-to-follow methodology presented in this book, featuring insight from experts including Simon Sinek and Brené Brown. Better communication will mean better business practice company-wide as well as increased employee engagement, happier clients and customers, and stronger profits. As the title suggests, Influential Internal Communication proves just how influential internal communications (IC) is, and the measurable impact it has on an organization's growth. For many organizations, IC often slips down the list of priorities when there are high pressure, high stakes business situations to cope with. This causes a sense of chaos and confusion within the organization that will - eventually - permeate to external customers and clients. Influential Internal Communication presents a clear, adaptable methodology that will help readers understand, diagnose and fix their own communication challenges, thereby transforming the chaos into calm. Backed up with data and statistics from industry reports on workplace culture, Influential Internal Communication is based on The Field Model and draws on research with CEO's, some of the best insights into people, organisations and chaos. The theory is backed up with real world case studies, showing how chaos can impact a range of organizations of varying size and industry. Written by the 2020 President of the Chartered Institute of Public Relations (CIPR), Influential Internal Communication will streamline any organization's IC practices, and help to drive engagement, efficiency and profit across the board.
