Abstract

The comparative response evaluation of M-ary phase-shift keying and M-ary quadrature amplitude modulation schemes is presented in this paper. The constellation diagrams for 16-PSK and 16-QAM are plotted to show the exact location of symbols, and the expressions for error probability are derived for both signaling schemes. The performance is compared by way of bit error probability and bandwidth efficiency. The simulated bit error rate graph plotted for different value of M are presented and compared with theoretical bit error rate plots separately. The combined BER graphs are also plotted for M = 16 and M = 64 for both signaling schemes and combined bandwidth efficiency graph plotted for M-ary PSK and M-ary QAM.
