Communication Systems

This book sets out to address the fundamental theory of communication systems, providing models for transmission systems and analytical tools for evaluating their performance. The relationship between performance and link parameters is developed. In particular, the book presents the principles of analog and digital modulation systems, including examples from well-established analog techniques, such as AM and FM, to more advanced digital formats, as CDMA and OFDM. There is coverage of deterministic and random signals, as well as transmission media and devices, bandpass signals, linear, amplitude, angular, digital and binary modulation.
