Capacity of a communication channel with quadrature phase-shift keying and phase quantization

Abstract

The influence of the number of phase quantization levels L on the capacity CM,L of a communication channel with additive white Gaussian noise (AWGN) was studied in a communication system using QPSK (4-PSK).
