Wireless physical layer secrecy has attracted much attention in recent years due to the broadcast nature of the wireless medium and its inherent vulnerability to eavesdropping. This book introduces various signal processing approaches to enhance physical layer secrecy in multi-antenna wireless systems. It focuses specifically on the signal processing aspects, including beamforming and precoding techniques for data transmission and discriminatory training schemes for channel estimation.

The content can be roughly divided into three parts: (i) data transmission, (ii) channel estimation and (iii) advanced applications. Even though many works exist in the literature on these topics, the approaches and perspectives taken were largely diverse. The discussions will cover cases with collocated and distributed antennas, i.e., relays. This book will also review recent works that apply these signal processing approaches to more advanced wireless systems, such as OFDM systems, multicell systems, cognitive radio, multihop networks etc. This book will allow readers to gain basic understanding of works on physical layer secrecy, knowledge of how signal processing techniques can be applied to this area, and the application of these techniques in advanced wireless applications. The authors hope to provide a more organized and systematic view of these designs and to lay a solid foundation for future work in these areas. By presenting the work from a signal processing perspective, this book should trigger more research interest from the signal processing community and further advance the field of physical layer secrecy along the described directions.[/expand]
