“…The result for the ratios R g , R 8 , R 16 and R 32 for different SNR values shows (see Figures 6 to 9) that the modulation type may be easily distinguished by just evaluating the ratios R(MOD, SNR). The Figure 6 presents the ratios R g , R 8 , R 16 and R 32 versus SNR (for, respectively, GMSK, 8-PSK, 16-QAM and 32-QAM modulations), for APD 0 = 0.1, in the case of an AWGN channel. The number of transmitted symbols has been set here to 10,000, and an oversampling factor of 8 has been used.…”
