EE 456

Examines the transmission of information (voice, video or data) over a noisy channel and presents the ideas and techniques fundamental to digital communication systems. Emphasis is placed on system design goals and the need for trade-offs among basic system parameters such as signal-to-noise ratio, probability of error, and bandwidth expenditure. Topics include binary baseband/passband data transmission, M-ary modulation techniques (QPSK, OQPSK, MSK, M-ASK, M-PSK, M-QAM and MFSK), signaling over band limited channels and methods to deal with ISI, and signaling over channels with amplitude and phase uncertainties.
