| Abstract: | M-QAM(Quadrature Amplitude Modulation) has a high frequency efficiency,but its quality will degrade largely under the multi-path environments,thus limits its application in wireless communications.This paper proposes a way to improve the performance of M-QAM in Rician fading,using maximum ratio and selective combining.It is expected that the method will gain wider use in reality. |

| Keywords: | QAM maximum ratio combining selective combining rician fading |
