Abstract
Spectral efficiency improvement with guaranteed communication consistency using channel coding techniques is the direction in which communication systems evolves. This paper presents M-ary PSK modulation performance over AWGN channel for higher M values. In this paper we simulate the performance of M-ary PSK modulation for higher orders of modulation applying irregular LDPC channel coding technique and obtain improved SNR as compared to uncoded M-ary Phase Shift Keying for M values varying from 4 to 4096.
