论文摘要
本文主要说明了M-ARY QAM和M-ARY PSK的位错误率性能，而RICIAN褪色通道的不同值的位错误率。信号体验无线通信系统中的多径传播，该传播会导致迅速的信号振幅波动，定义为褪色。里克里亚人褪色是一个小信号褪色。里克里亚人褪色是一个假设模型，是通过单独取消无线电信号产生的无线电传播不一致的假设模型，结果信号通过几个不同的路径在接收器中达到。在这种情况下，至少有一条目的地路径正在延长或缩短。从本文中，可以观察到，当信号与噪声比增加的玛丽QAM和M-ARY PSK（例如256 QAM，64 psk等）的分贝时，位错误率的值降低。在本文中，使用MATLAB模拟也显示了M-QAM和M-PSK的星座图。本文还包括了随着SNR固定值的多样性顺序的增加，位错误率的下降。多样性是一个有影响力的接收器系统，可改善接收的信号强度。
This paper mainly illustrates the Bit error rate performance of M-ary QAM and M-ary PSK for different values of SNR over Rician Fading channel. A signal experiences multipath propagation in the wireless communication system which causes expeditious signal amplitude fluctuations in time, is defined as fading. Rician Fading is a small signal fading. Rician fading is a hypothetical model for radio propagation inconsistency produced by fractional cancellation of a radio signal by itself and as a result the signal reaches in the receiver by several different paths. In this case, at least one of the destination paths is being lengthened or shortened. From this paper , it can be observed that the value of Bit error rate decreases when signal to noise ratio increases in decibel for Mary QAM and M-ary PSK such as 256 QAM, 64 PSK etc. Constellation diagrams of M-QAM and M-PSK have also been showed in this paper using MATLAB Simulation. The falling of Bit error rate with the increase of diversity order for a fixed value of SNR has also been included in this paper. Diversity is a influential receiver system which offers improvement over received signal strength.
