Abstract :
: Modern wireless Communication system use digital modulation schemes because of its many advantages over the analog modulation schemes. In this paper we analyze various M-ary FSK, M-ary PSK and M-ary PAM modulation schemes using simulink model of MATLAB taking BER as measure of performance when the system is subjected to AWGN and fading channel. Based on these performances a modulation scheme is suggested that provides low BER at low SNR. The simulation results for these methods show that the performance of the system is good in case of AWGN channel as compared to other fading channels. Multipath fading is the very important factors that affect the performance of a communication system. Simulations are used to compare the performance and tradeoffs of M- ary techniques, including analysis of BER in the presence of Additive White Gaussian Noise (AWGN) and multipath fading environment. The performance of different M-ary FSK, M-ary PSK and M-ary PAM methods are compå for various types of the fading channels using the MATLAB simulation. < clear="all" style="page-eak-before:always;mso-eak-type:section-eak" />
