This detailed introduction presents the theory of digital modulation and coding underpinning the modern design of modems for telecommunications. From baseband and passband modulation and demodulation to sequence estimation, turbo codes, and the Viterbi algorithm, a wide range of key topics is covered, whilst end-of-chapter exercises test students' understanding throughout.
