ABSTRACT

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book considers applications of chaotic electronics in telecommunications at some levels. It provides an introduction to spread spectrum communications, highlighting the key performance issues for Direct Sequence-Code Division Multiple Access (DS-CDMA). The book deals with chaos-based asynchronous DS-CDMA systems. It discusses information sources using chaotic dynamics, also addressing briefly the use of chaos in encryption. The book also provides an overview of digital communications. It focuses on chaotic modulation schemes, highlighting the problems associated with coherent detection of chaotic transmissions. The book analyzes the performance of slow- and fast-frequency-hopping variants of FM-DCSK in multipath environments. It discusses noise filtering in chaos-based communications. The book addresses statistical analysis and design strategies for chaotic systems. The book also focuses on chaos-based noise generation in silicon.
