Analysis of the additive white Gaussian noise bit error rate and signal to noise ratio under the relationship between the mapped BER- signal to noise ratio curve, and and physical curves for comparison.)

BP源代码共享！希望对大家有帮助今天编了个预测程序，效果不是很好，但里面一些基本算法希望给刚学的人有所帮助！同时也希望高人帮忙指点一下，我这个程序要怎么样预测效果才会好点，谢谢！(BP to share the source code! Hope everyone has to help today编了个prediction procedure, the effect is not very good, but inside some of the basic algorithm would like to just help people to learn! At the same time also hope that an expert advice to help you, I like this process to predict how the effect will be a good point, thank you!)

这个matlab代码是实现基于最小二乘算法的常数模算法。较最小均方误差算法，该算法收敛速度较快。(Matlab code to achieve the constant modulus algorithm based on least squares algorithm. Than the minimum mean square error algorithm, the algorithm converges faster.)
