连续相位调制CPM的软输入软输出SISO解调(Continuous phase modulation CPM soft input soft output SISO demodulator)

The program simulates convolutional code using soft-decoding viterbi algorithm. The choice of generator matrix (G) determines the code rate (1/R) and constraint length of the code (K).

基于小波变换的功率谱估计MATLAB仿真代码，包括小波变换的基本原理实现，mallat算法的实现，经典功率谱和现代功率谱估计的主要方法仿真比较。(Based on wavelet transform power spectrum estimation MATLAB simulation code, including the basic principles of wavelet transform to achieve, mallat Algorithm, classic and modern power spectrum power spectrum estimation of the primary means of comparison and simulation.)

该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益。(AF and DF simulation procedure code)

众多恒虚警检测（CFAR）算法都是基于单元平均（CA:Cell Avarage）的方法，该算法需要较大的运算量。本程序给出了基于有序统计（OS:Order Statistic）的CFAR检测算法，弥补了CA_CFAR检测算法的不足，同时还配有本人硕士毕业论文中的检测图像以及实验结果，具有一定的参考价值。(CA_CFAR algorithm often requires large computational complexity. OS_CFAR algorithm is presented, which can make up the disadvantages in CA_CFAR. In the meantime, some processed images are given, which has a high value of reference.)

此算法是基于matlab的MFCC特征提取算法，其中包括了分帧、归一化等步骤和代码，非常好用，结果是24维的向量(This algorithm is based on MFCC feature extraction algorithm matlab, including the framing, normalization and other steps and code, very easy to use, the result is 24-dimensional vector)

时间序列数据分析中的梅林变换工具箱，可加载后直接调用里面的函数。(Time-series data analysis in the Mellin transform toolbox.)

2D FDTD Codes with: standar formulation, flux density formulation, Mur ABC 1st and 2nd order, for TM mode

本文件包含一个word文档，详细讲解互信息的计算，以及一个txt文档，包含MI的matlab源代码。(This document contains a word document, explain in detail the calculation of mutual information, as well as a txt file, including MI, Matlab source code.)
