这里的DDS(直接数字合成)是我在MATLAB中用Simulink基本模块搭建起来的模型,仿真DDS信号的产生,并有一个M文件实现与模型同等的功能,MATLAB爱好者一定不要错过(I build the DDS model using simulink basic model to simulate the DDS source, associated a M file realizing the same function as the model,and,the MATLAB lovers must not miss)

使用qam星座调制方式下的，空时编码STBC的误码率(BER)仿真(The use of QAM modulation constellation manner, the space-time coding STBC BER (BER) simulation)

slam进阶学习，老外做的，很完善的东西，对于同时定位与地图创建的friend有很大的帮助（第二课）(err)

觉得很好的一个Matlab程序想和大家一起分享，互相学习。(A Matlab program feel good and you want to share, learn from each other.)

说明：  该程序是用matlab语言实现无线通信领域ofdm的描述，读者可以一试(that the procedure was used Matlab language OFDM wireless communications description, the reader can be a trial)

一个正弦波利用DCT，FFT变换后稀疏化，然后应用压缩感知实现压缩，并有仿真图例说明重构效果。重构算法采用线性规划和OMP算法等，是一个初学CS入门的好例子。(A sine wave using DCT, FFT transform sparse, and then apply compressed sensing to achieve compression, and a legend reconstruction simulation results. Reconstruction algorithm using linear programming and OMP algorithms, is a good example of beginner CS entry.)

In mathematics, the discrete-time Fourier transform (DTFT) is one of the specific forms of Fourier analysis. As such, it transforms one function into another, which is called the frequency domain representation, or simply the "DTFT", of the original function (which is often a function in the time-domain).(This file includes matlab source code about DTFT and also includes explanation report)

by using this code , you have to get the LBPH of an face input .

简单的获取分类器融合矩阵的matlab程序，利于初学者理解融合矩阵的含义(Get simple classifier fusion matrix matlab program, which will help beginners to understand the meaning of the integration matrix)

滤掉低频段和高频段频率，分波段滤波，过滤掉噪声干扰，绘制功率谱密度曲线(Filter out the low and high frequency bands, filter in different bands, filter out the noise interference, and draw the power spectral density curve.)
