Barry discusses several digital communication techniques, including pulse-code modulation (PCM), differential pulse-code modulation (DPCM), and quadrature amplitude modulation (QAM). PCM involves sampling the analog signal and converting it into a digital signal, while DPCM uses the previous sample to predict the current sample, reducing the amount of information required to transmit the signal. QAM is a modulation technique that encodes digital information onto a carrier wave by varying the amplitude and phase of the wave. : The text emphasizes clear assumptions—such as function
: Designing pulses (like the raised-cosine pulse) that eliminate ISI at the sampling instants.
A core focus of the book is how to map digital bits onto analog waveforms. It details standard and advanced modulation schemes, including: Phase Shift Keying (PSK) Quadrature Amplitude Modulation (QAM) Frequency Shift Keying (FSK) 3.

A critical section of the book focuses on how to map digital bits into analog waveforms (modulation) and how to extract those bits back at the receiver (demodulation) despite channel degradation.
Utilizing Maximum A Posteriori (MAP) and Maximum Likelihood (ML) decision rules to minimize bit error rates (BER).
