说明：  平方根 求解线性方程组的解 数值计算(The square root of the solution for solving linear equations)

在频率域实现信号的频移，然后再变换回时间域的信号(In the frequency domain, the frequency shift signal is achieved, and then transformed back into the time domain signal)

仿真实现了MUSIC、Beamformer、Capon功率谱，并未实现线性预测功率谱估计（未找到方法）。由实验结果我们可以得出结论MUSIC的估计效果最好，它可以区分800、850处来波，其他角度也可区分。(Simulation of MUSIC, Beamformer, Capon power spectrum, did not realize the power spectrum estimation linear prediction (not way to find). From the experimental results, we can draw the conclusion MUSIC best estimate of the effect, it can be distinguished to wave at 800, 850, other angles can also be distinguished.)

this is the source code for Matlab & simulink for digital communication. this folder contains all the matlab code in the textbook.

说明：  matlab使用程序百例，适用于新手学习研究(Examples)

here i have provided a matlab code in which we have the gold price of laast 4 yrs.we have predicted and showed it using a matlab code.

一个基于adaboost的人脸检测分类器训练程序，用MATLAB写的，希望能和大家分享(a face detect programme based on adaboost which is written by matlab)

说明：  使用icosaedron细分方法建立球面三角模型。(Returns the triangulated model of a sphere using the icosaedron subdivision method. )

基于RSSI的测距定位算法，可以直接自己写demo然后进行测试，十分的方便(RSSI-based distance positioning algorithm can write your own demo and then test, very convenient)

一种改进的Toeplitz算法，具有更好的稳定性，更高的分辨力(A kind of improved Toeplitz algorithm, it has better stability, higher resolution )
