一个采用slm实现ofdm系统降低峰均比的程序，效果挺不错的。(An ofdm system using slm achieve PAPR reduction program, the effect is very good.)

原始信号、噪音均为正弦信号的LMS噪音抵消系统实现(The original signal and noise are sinusoidal signals in noise canceling system to achieve LMS)

when SNR is high , 1st sample estimator provides good estimate of A. it has no noise effect . so we don’t need averaging effect to reduce noise when SNR is high. However variance is still low in sample mean estimator which shows that in reality ,sample mean is good estimator than 1st sample estimator. So, for high SNR, we do not need to reduce the effect of noise by averaging. or we can say that for high SNR let say >1000 , 1st sample estimator got reduced noise. But as for as variance is concerned , the sample mean has low variance for high SNR as well.
