说明：  最优多用户检测，即最大后验概率的算法，主要是用于多用户检测中(Optimal multi-user detection, that is, maximum a posteriori probability algorithm, mainly used for multi-user detection)

Biomedical signals processing

基于MATLAB软件的OFDM系统仿真的调制解调的对比！(Based on comparison of OFDM system simulation software MATLAB modulation and demodulation!)

说明：  永磁同步电机matlab，simulink仿真(Simulation of PMSM Based on MATLAB and Simulink)

MATLAB实现的简单的OFDM模型源代码 这个Matlab程序是关于OFDM调制的。这里使用了BPSK调制，显示OFDM在误码率上的下降。(BPSK modulation with BER with and without OFDM)

余弦变换压缩，用于图像压缩，压缩比高，且压缩后图像质量仍然很好。适用于灰度图象。(Cosine Transform compression for image compression, compression ratio, and compressed image quality is still good. Apply to the gray-scale image.)

Based on An Efficient Procedure for Nakagami-m Fading Simulation, Norman C. Beaulieu, Christine Cheng

常用分形matlab程序（经测试）具体为几种常见混沌时间序列matlab实现(Commonly used fractal matlab program (tested) specific for several common realization of chaotic time series matlab)

基于小波神经网络的横摇运动和预测的程序matlab程序(Based on wavelet neural network and prediction of roll motion matlab process procedures)

共生矩阵的实现及特征提取方法，里面包含了各个特征向量提取的子程序，可以在其他程序中直接调用。(co-occurrence matrix and the realization of feature extraction methods, each of which contains a feature vector extraction subroutine, the other procedures can be called directly.)
