最速下降法，是数值分析中很重要的一种，源码为其在matlab中的实现。(Steepest descent method, numerical analysis is a very important one in the matlab source code for its realization.)

说明：  用MATLAB仿真的数字下变频程序，变频，滤波未用matlab函数，而是用代码完成，便于移到DSP或FPGA上。供参考。(Using MATLAB simulation of digital down conversion process, conversion, filtering is not used matlab functions, but with code completion, easier to move on a DSP or FPGA. For reference.)

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.
