The demodulation process depends on the type of modulation employed. For DSB-AM and SSB-AM, the demodulation method is coherent demodulation, which requires the existence of a signal with the same frequency and phase of the carrier at
Pulse-Amplitude Modulation (PAM) involves varying the signal amplitude according to the analog input signal. Pulse-Width Modulation (PWM) adjusts the width of the pulse based on the input signal, while Pulse-Position Modulation (PPM) changes the position
A QAM signal received through an additive white Gaussian noise (AWGN) channel can be converted into a point in the 2-D vector space. The MATLAB function berawgn() can be used to calculate the theoretical BER of various modulation and demodulation methods. The chapter then compares the BER ...
