Aim of course

Knowledge of fundamental digital modulation and detection techniques

Subject of course

1. Introduction:  Outline, basic facts, communication channels, historic perspective, related courses, literature

2. Pulse amplitude modulation (PAM) fundamentals:  Baseband PAM, passband PAM (including spread spectrum modulation and CDMA), transmit spectrum, spectral efficiency, symbol alphabet design, problems

3. Elementary passband PAM systems:  Channel, elementary receiver, equivalent discrete-time baseband system, intersymbol interference, Nyquist pulses, eye diagrams, symbol and bit error probability, matched filter, problems

4. Equalization:  Linear equalizer (zero-forcing design, mean-square-error design, adaptive equalizer, fractionally spaced equalizer), decision-feedback equalizer, problems

5. Optimum sequence detectors:  MAP and ML sequence detectors, probability of a sequence error, signal design, incoherent ML sequence detector, problems

6. ML sequence detectors for passband PAM:  Spectral factorization, whitened matched filter, trellis diagram, Viterbi algorithm, problems

7. Multipulse modulation and detection techniques:  Orthogonal multipulse modulation (transmit spectrum, spectral efficiency, FSK, MSK, ML sequence detector, matched filterbank, generalized Nyquist criterion, error probability, incoherent ML sequence detector), orthogonal multipulse PAM (transmit spectrum, spectral efficiency, ML sequence detector, multicarrier modulation, DMT, OFDM), problems

8. Channel capacity:  Basic example, capacity of the AWGN channel, the promise of channel capacity, basic facts of channel coding (threshold SNR, coding gain, bandwidth expansion), problems
