Course Description: Introduction to Digital Communications, including: Random variables and probability distributions, signal-to-noise ratio (S/N), and probability of error. Synchronous digital modulation techniques, including: Amplitude-shift keying (ASK), frequency-shift keying (FSK), phase-shift keying (PSK), quadrature phase-shift keying (QPSK), minimum-shift keying (MSK), and Gaussian minimum-shift keying (GMSK). Quadrature digital modulation techniques, including: Orthogonal frequency-division multiplexing (OFDM). Comparison of digital modulation techniques, including: Bandwidth, power spectral density, and probability of error. Introduction to Information Theory, including: Channel capacity, source coding, channel coding, inter-symbol interference (ISI), and error correction coding techniques.
