WebbLet us evaluate the average bit error rate (BER) of this system using a low complex but accurate method. Note that the BER depends on random fading, and it is a nonlinear function of the SNR. The nature of the nonlinearity is a function of the modulation/detection scheme employed [ 13 ]. Webbbaseband simulation models. * Digital modulation techniques covered: BPSK and its variants, QPSK and its variants, M-ary PSK, M-ary QAM, M-ary PAM, CPM, MSK, GMSK, M-ary FSK. * Monte Carlo simulation for ascertaining performance of digital modulation techniques in AWGN and fading channels - Eb/N0 Vs BER curves.
