说明：  对心音信号进行BT功率谱估计及切比雪夫1滤波的matlab程序，可粗略提取心音频率(PSD BT chey1 matlab)

循 环 相 关 谱检 测 法 的 检 测性 能 优 于循环 相 关 谱 系 数 检 测法,但 循环 相 关 谱检 测法 的 性 能 受 噪 声 功 率 估 计 误 差 影 响 大,而 循环 相 关 谱 系 数 检 测 法 不 需 要 已 知 噪 声 功 率,实 用性 更 强(Circular correlation spectrum inspection measurement method of inspection measurement can be optimal in cyclic correlation spectrum coefficient measuring method, but closed loop phase spectrum detection method of measuring performance is affected by the noise power estimation error is large, and cyclic correlation spectrum coefficient test don t need to noise power ratio is known, use sex is stronger)

本程序是用于信号相关分析的实验程序。 主要功能是计算和比较几种信号的相关函数。( This procedure is experimental procedure for signal correlation analysis. The main function of the correlation function is calculated and compared several signals.)

仿真分析了FFT的补零、泄露、加窗、以及FFT分辨率等问题(Simulation analysis of the FFT of zeros, leakage, windowing, and FFT resolution issues)

最优化算法中最速下降法的Matlab源码，很不错的源码，希望对你有用。(Optimization algorithm in the steepest descent method of Matlab source code, it is a good source, I hope useful to you.)

关于协作通信方面的放大转发、译码转发、编码协作的介绍，对学习协作通信非常有帮助。(About cooperative communications amplification forwarding, forwarding decoding encoded collaboration introduction learning collaborative communication is very helpful.)
