This course introduces principle of digital communications. It covers Gaussian and noise processes. PCM systems, digital multiplexing, line coding, pulse shaping, and baseband transmission techniques. Repr-

esentation of signals, vector equivalent channel models, and design

of signal sets. Techniques of digital modulation, detection in AWGN channel, matcced filter optimum and maximum-likelihood receivers, probability of error, synchronization, and performance trade-offs. Intersymbol interference (ISI) and equalization. Spread spectrum sy-

stems, and multiple access.
