Abstract

There is always a search for digital modulation technique that has efficient bandwidth and low bit error rate at a relatively low signal to noise power. Considering this requirement, in this paper we provide a general theoretical analysis of various M-ary PSK modulation for M = 2,4,8,16,and 32, M-ary QAM for M=4,16 and 64 and MaryDPSK for M=2 and 4 using MATLAB Simulink taking BER as measure of performance when the system is subjected to Additive White Gaussian Channel. In this paper we take up bandwidth efficient linear digital modulation schemes and compare its performance based on their theoretical BER over AWGN and proves that increasing the value of M results in increase of BER with the increase in data rate.
