说明：  遗传算法优化BP神经网络程序,很不错的，值得学习(GA for BP neural network training)

说明：  计算光纤模场分布和传播常数，输入模式的阶数，计算得到各类模式的模场分布。直接运行main，在其中修改参数，至少可以计算5层光纤结构。(Calculation of optical mode field distribution and propagation constant, the order input mode, calculated by various types of mode-mode field distribution. Direct run main, in which the modified parameters can be calculated for at least 5 layer fiber structure.)

lms自适应算法的均衡器的设计，包括详细的流程(lms adaptive equalizer algorithm design, including detailed process)

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.
