Introduction to Digital Communications: Delta Modulation. Baseband transmissions of digital
signals: bit error rate, ISI and M-ary PAM transmission. Passband transmissions of digital signals:
Coherent Digital Modulation Techniques, including amplitude-shift keying (ASK), frequency-shift
keying (FSK) and phase-shift keying (PSK), Differential PSK, Quadriphase shift keying (QPSK), Mary PSK, Hybrid Amplitude/Phase Modulation (M-ary QAM), Minimum-shift keying (MSK), and
Gaussian MSK (GMSK). Comparison between different Digital Modulation Techniques, including
modulated signal bandwidth, signal-to noise ratio (SNR) and probability of bit error.
