本资料介绍VC与matlab混合编程的知识，介绍较为详尽。(How to program with VC and matlab)

用MATLAB实现d2d通信中的模式选择(D2D mode seclection MATLAB)

用基于 Matlab 的小容量 FFT (比如 256×256)程序，将取样窗口划分为 若干个全等的小矩形,对每个小矩形内离散点的复振幅作 FFT 变换,然后将所有变 换结果叠加，再乘以复数相位因子,相当于对整个物面上点进行菲涅耳衍射计算， 利用这种方法可以迅速的实现高精度的轴对称傍轴光学系统中的激光衍射计算 (With a small volume based on Matlab FFT (eg 256 × 256) procedure to sample window divided into a number of small identical rectangles, each small rectangle of discrete points within the complex amplitude for the FFT transform, and then transform the results of all the superposition multiplied by the complex phase factor, the equivalent point on the object plane Fresnel diffraction calculation, the use of this method can rapidly achieve high-precision optical system axis of symmetry in the paraxial calculation of laser diffraction)

当时间间隔足够小的时候，速度和加速度的瞬时值可用平均值代替。">

说明：  该程序计算了2*2的MIMO信道在瑞利衰落下、BPSK调制下迫零均衡的误比特率，并有理论值和仿真值的对比(The program calculates the bit error rate of 2* 2 MIMO channel in Rayleigh fading, BPSK modulation, the zero forcing equalizer, and a comparison of the theoretical values ​ ​ and simulation values)

包括调制，解调，信噪比计算，抑制载波型差分相位调制，实现典型相关分析，music高阶谱分析算法，随机调制信号下的模拟ppm，是小学期课程设计的题目，采用了小波去噪的思想，针对EMD方法的不足。( Includes the modulation, demodulation, signal to noise ratio calculation, Suppressed carrier type differential phase modulation, Achieve canonical correlation analysis, music higher order spectral analysis algorithm, Random ppm modulated analog signal under Is the topic of the elementary school stage curriculum design, Using wavelet denoising thought, For lack of EMD.)

离散信号的时域分析，输出各种离散信号的波形图，有利于各初学者理解揣摩(Time domain analysis of discrete signals, the output waveform of various discrete signals, try to figure out is conducive to the beginner to understand)

Matlab语音处理工具箱，很多语音处理m文件(Speech Processing Toolbox Matlab, many voice processing document m)

简单易用入门的MATLAB源程序，希望能够给大家带来帮助！(Easy to use entry of the MATLAB source code, hoping to give us some help!)
