这是一个matlab代码，实现mfsk信号源的产生。(This is a matlab program ,it is a m file to create mfsk source.)

码分多址，是在无线通讯上使用的技术，CDMA 允许所有的使用者同时使用全部频带(1.2288Mhz)的系统仿真(CDMA is used in wireless communications technology, CDMA allows all users to simultaneously use all bands (1.2288Mhz) System Simulation)

在matlab中，绘制图像的灰度直方图，并均衡化复原图像(In matlab, rendering the image histogram, and equalization restored image)

16QAM-matlab simulation(16QAM- Matlab simulation)

产生一个RGB立方图：R(红)-G（绿），R（红）-B（蓝），G（绿）-B（蓝）(Color model. Use Matlab to create six (6) color images of size 512×512 in ppm format, each of which represents one of the six sides of the RGB color cube.)

小波包分析提取振动信号中的特征频率，有较好的参考价值，借鉴了主成分分析算法（PCA）。( Wavelet packet analysis to extract vibration signal characteristic frequency, There are good reference value, It draws on principal component analysis algorithm (PCA).)

此源码程序是自适应滤波中的自适应均衡器在MATLAB中对其就行了仿真，是自适应滤波的一种应用(The source process is adaptive filtering in the adaptive equalizer in MATLAB on the line in their simulation is a kind of adaptive filtering applications)

系统辨识的作业，是自己写的，有需要的可以参考参考(System identification of the work is your own writing, there is a need that can refer to reference)

说明：  基于匹配滤波器输出的非线性判决反馈DF检测器(This paper introduees cause of formation of MAI in CDMA systems, and Points out that multi-user Deteetion(MUD) teehnology can improve eapability and performanee of CDMA through suppressing MAI)
