产生不同频率、不同幅度的两种正弦波信号 对两个信号进行叠加并做频谱分析 还原原来两个信号（LPF)(Produce different frequency, the two sine wave signals of different magnitudes of the two signals are superimposed and do spectral analysis to restore the original two signals (LPF))

matlab编的模拟自由扩散的过程，初学者适用(simulation of free walk )

说明：  基于有限反馈的MIMO_空分复用预编码优化设计(MIMO_ based on limited feedback precoding spatial multiplexing Optimal Design)

一篇关于空时码的论文，我看过了，觉得不错，希望对大家有用(A thesis about the space-time code, I have read, I feel good, hope to be useful)

This MATLAB exercise designs and implements a pitch period detector based on detecting and tracking peaks in the autocorrelation of the LPC error signal during regions of voiced speech. The pitch detection procedure is called the SIFT (Simple Inverse Filtering Tracking) method. The SIFT pitch period detector uses a secondary autocorrelation peak in order to detect and correct pitch period detection errors due to effects such as pitch period doubling and related phenomena.

bessel函数求零点，给一个参数x,则可以求出x附近的bessel函数的零点。(bessel function of order zero, to a parameter x, you can find the bessel function of x near zero.)
