适合初学者学习,好的算法和程序,非常需要的可以下载看看(Suitable for beginners to learn, good algorithms and procedures, very much needed to download to see.)

在信号处理、图形计算和相关学科中，混叠是一种效应，当对不同的连续信号进行数字采样时，混叠会导致它们变得不可区分。当这种情况发生时，原始信号不能从数字信号单声道重建信号。信号汉明窗的响应与冯·汉恩的非常相似，尽管它的旁瓣较小。与Von Hann相比，Hamming窗的优点是它产生了较低的卷曲和过渡区。

串口通讯的一个类，已经在用，分享给大家。(serial port communication file.)

This function generates an Additive White Gaussian Noise (AWGN) sample at every call. Its beauty lies in its simplicity! The generated sample set will have zero mean and a standard deviation of 1. Therefore, one can simply scale the output samples by a different standard deviation to generate different noise profiles. To do this scaling, simply multiply the sample with the standard deviation of your choice. This is a very versatile function that can be used in communication system simulations and random number generation in various applications. I have used it in the past while working with channel encoder and decoder simulators.
