This book discusses computational complexity of High Efficiency Video Coding (HEVC) encoders with coverage extending from the analysis of HEVC compression efficiency and computational complexity to the reduction and scaling of its encoding complexity. After an introduction to the topic and a review of the state-of-the-art research in the field, the authors provide a detailed analysis of the HEVC encoding tools compression efficiency and computational complexity. Readers will benefit from a set of algorithms for scaling the computational complexity of HEVC encoders, all of which take advantage from the flexibility of the frame partitioning structures allowed by the standard. The authors also provide a set of early termination methods based on data mining and machine learning techniques, which are able to reduce the computational complexity required to find the best frame partitioning structures. The applicability of the proposed methods is finally exemplified with an encoding time control system that employs the best complexity reduction and scaling methods presented throughout the book. The methods presented in this book are especially useful in power-constrained, portable multimedia devices to reduce energy consumption and to extend battery life. They can also be applied to portable and non-portable multimedia devices operating in real time with limited computational resources.

It also includes block diagrams and/or circuits of modulators, demodulators, carrier recovery, clock recovery and comparison with other schemes. In its comprehensive overview of digital modulation applications, it seeks to offer a practical understanding of conventional, fixed microwave terrestrial communications, mobile wireless, and mobile satellite communications.

This comprehensive study examines the case of AM stereo and subsequent technologies to demonstrate the FCC's evolution from stern to reluctant regulator. It also examines emerging technologies, such as multichannel television sound, digital audio broadcasting, and high definition television, and discusses their impact on the evolution of broadcast regulation. In the 1980s the tension between governmental control and the marketplace resulted in the FCC's deregulation of TV and radio, electing to set only technical operating parameters and allowing legal operation of any system that meets those minimal standards. Huff argues that this approach is likely to influence regulatory approaches to other new developments in broadcast technologies. The extensive overview of the industry and the study of the interrelationships between the technologies will appeal to communication scholars in the fields of radio and television as well as interest industry professionals.

This book presents physical-layer security as a promising paradigm for achieving the information-theoretic secrecy required for wireless networks. It explains how wireless networks are extremely vulnerable to eavesdropping attacks and discusses a range of security techniques including information-theoretic security, artificial noise aided security, security-oriented beamforming, and diversity assisted security approaches. It also provides an overview of the cooperative relaying methods for wireless networks such as orthogonal relaying, non-orthogonal relaying, and relay selection.Chapters explore the relay-selection designs for improving wireless secrecy against eavesdropping in time-varying fading environments and a joint relay and jammer selection for wireless physical-layer security, where a relay is used to assist the transmission from the source to destination and a friendly jammer is employed to transmit an artificial noise for confusing the eavesdropper. Additionally, the security-reliability tradeoff (SRT) is mathematically characterized for wireless communications and two main relay-selection schemes, the single-relay and multi-relay selection, are devised for the wireless SRT improvement. In the single-relay selection, only the single best relay is chosen for assisting the wireless transmission, while the multi-relay selection invokes multiple relays for simultaneously forwarding the source transmission to the destination.Physical-Layer Security for Cooperative Relay Networks is designed for researchers and professionals working with networking or wireless security. Advanced-level students interested in networks, wireless, or privacy will also find this book a useful resource.
