Higher data rate modulation scheme is one of the significant criteria but minimizing the bit error rate is one of the major aspects in wireless communication. This paper shows that using the binary reflected gray code to label the signal constellation results in the lower possible BER and SER. Modulation scheme which are skilled enough to carry more bps are more resistant to mistakes. These errors are produced mainly due to the noise and interference that occurs in the channel. The most widely used modulation schemes in wireless communication now a days are M-ary PSK and M-ary QAM. In this paper Gray codes are used for M-ary PSK and M-ary QAM modulation technique over AWGN channel and performance comparison of different modulation techniques has been shown in terms of BER and SER. |
