The primary focus of this book is communication system, including algorithms that are particularly suited to DSP implementation. Software and hardware tools are introduced, as well as FIR and IIR digital filters and the FFT. This book also discusses modulators and demodulators for classical analog modulation methods such as amplitude modulation (AM), double-sideband suppressed-carrier amplitude modulation (DSBSC-AM), single sideband modulation (SSB), and frequency modulation (FM). The second half of the book explores digital communication methods leading to the implementation of a telephone-line modem. This new edition also incorporates a comprehensive discussion of Orthogonal Frequency Division Multiplexing (OFDM), which is particularly partinent as the world is heavily turning toward using wireless wideband communication. Methods for adaptive equalization, carrier recovery, and symbol clock tracking are presented as well, with suggestions for additional experiments.//yeni
