Digital Communications: Introduction to Communication Systems (Synthesis Lectures on Communications)
by Jerry D. GibsonThis book develops the concepts for the transmission of digital information sequences through analog, band limited channels, including the topics of pulse shaping, channels with amplitude and delay distortion, eye patterns, zero forcing and mean squared error equalization, and data scrambling. The text considers the effects of noise in digital communications, developing the fundamental ideas of signal space, optimum symbol-by-symbol detection, and modulation system design, with particular emphasis on maximum likelihood and maximum a posteriori detection and system performance comparisons based on energy per bit to noise ratio and average error probability. The key technique of maximum likelihood sequence estimation is also developed. Tutorial coverage provides an introduction to block and convolutional codes for error control coding, including coding and decoding methods for error detection and correction, tree and trellis representations, and Viterbi decoding. Some performance comparisons for selected codes in terms of energy per bit to noise ratio versus bit error probability are presented. This book examines joint coding and modulation methods such as constant envelope modulation and trellis coded modulation, including examples such as minimum shift keying and offset quadrature phase shift keying.

Digital Communications 1: Source and Channel Coding
by Didier Le Ruyet Mylène PischellaThe 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.
Digital Communications 2: Directed and Practical Work
by Safwan El Assad Dominique BarbaIt is a complete training in digital communications in the same book with all the aspects involved in such training: courses, tutorials with many typical problems targeted with detailed solutions, practical work concretely illustrating various aspects of technical implementation implemented. It breaks down into three parts. The Theory of information itself, which concerns both the sources of information and the channels of its transmission, taking into account the errors they introduce in the transmission of information and the means of protect by the use of appropriate coding methods. Then for the technical aspects of transmission, first the baseband transmission is presented with the important concept and fundamental technique of equalization. The performance evaluation in terms of probability of errors is systematically developed and detailed as well as the online codes used. Finally, the third part presents the Transmissions with digital modulation of carriers used in radio transmissions but also on electric cables. A second important aspect in learning a learner's knowledge and skills is this book. It concerns the "Directed Work" aspect of a training. This is an ordered set of 33 typical problems with detailed solutions covering the different parts of the course with practical work. Finally, the last aspect concerns the practical aspects in the proper sense of the term, an essential complement to training going as far as know-how. We propose here a set of 5 practical works.

Digital Constitutionalism: The Role of Internet Bills of Rights (Routledge Research in the Law of Emerging Technologies)
by Edoardo CelesteInvestigating the impact of digital technology on contemporary constitutionalism, this book offers an overview of the transformations that are currently occurring at constitutional level, highlighting their link with ongoing societal changes. It reconstructs the multiple ways in which constitutional law is reacting to these challenges and explores the role of one original response to this phenomenon: the emergence of Internet bills of rights. Over the past few years, a significant number of Internet bills of rights have emerged around the world. These documents represent non-legally binding declarations promoted mostly by individuals and civil society groups that articulate rights and principles for the digital society. This book argues that these initiatives reflect a change in the constitutional ecosystem. The transformations prompted by the digital revolution in our society ferment under a vault of constitutional norms shaped for ‘analogue’ communities. Constitutional law struggles to address all the challenges of the digital environment. In this context, Internet bills of rights, by emerging outside traditional institutional processes, represent a unique response to suggest new constitutional solutions for the digital age. Explaining how constitutional law is reacting to the advent of the digital revolution and analysing the constitutional function of Internet Bills of Rights in this context, this book offers a global comparative investigation of the latest transformations that digital technology is generating in the constitutional ecosystem and highlights the plural and multilevel process that is contributing to shape constitutional norms for the Internet age.

The Digital Currency Challenge: Shaping Online Payment Systems through US Financial Regulations (Palgrave Pivot)
by P. Carl Mullan<p>Private online digital currency systems offer people accessible, convenient, and inexpensive everyday financial tools outside of traditional bank-owned and operated platforms. Digital currency systems facilitate local and international fund transfers, online and offline payments, and simple cash-to-digital everyday financial products without the need for a conventional bank account of any retail bank product. Over the past several years, Bitcoin has grown into an efficient person-to-person and person-to-business payment system without the backing of any bank or financial institution. This phenomenon is producing a new level of an on- and offline commerce and a society much more attuned to digital currency systems. <p>The Digital Currency Challenge details how new 2007-2008 U.S. legal issues surrounding digital currency products forced companies from the U.S. market and caused the Treasury Department to enact stricter regulations. Mullan profiles new and innovative present day digital currency systems, such as Bitcoin, and illustrates how software designers and monetary theorists use new technology to circumvent current U.S. regulations. This work also explains how new digital currency systems are not just software products, but tools providing financial freedom to people in countries all around the world.</p>
