Calculation-of-special-functions

fastica法的matlab工具包，是一组程序(FastICA matlab law Toolkit, is a set of procedures)

Automatic toll collection system

本程序是自己写的，经过验证的，瑞利衰落信道下的BPSK信号仿真(This program is written in their own, after verification, simulation of BPSK signals in Rayleigh fading channels)

说明：  使用波动方程有限差分模拟瑞雷波的传播，包括模拟和成像，可以更改检波器位置信息(surface wave modeling and display)

该程序模拟仿真QPSK传输系统，对通信系统学习有帮助。(Simulation program to realize QPSK transmission system)

说明：  matlab的几个经典程序，有100的。(matlab several classical procedures, has 100.)

实现以下功能：装载信号；完成信号的单尺度一维离散小波分解；从系数中重构低频部分和高频部分；显示高频和低频部分；由小波逆变换恢复信号；多层一维分解；提取系数的低频和高频部分；重构第3层的低频系数；重构第1、2、3、4、5层的高频信号；重构原始信号并显示(Achieve the following functions: load signal complete signal single-scale one-dimensional discrete wavelet decomposition reconstructed from the coefficients in the low frequency and high frequency display high-frequency and low frequency restored by the inverse wavelet transform signal multi-layer one-dimensional decomposition extraction coefficient of low frequency and high frequency reconstruction of 3-layer low-frequency coefficients reconstruction of the first layer of high-frequency signal 1,2,3,4,5 reconstruct the original signal and display)

数据处理，数据整形，简单实用，用于对原始数据预处理(Data processing, data shaping, simple and practical, used for pretreatment of raw data.)

混沌加密解密语音 aes加密解密语音 验证加密的混沌性质，和恢复波形(apply chaotic encryption and decryption to wav apply AES encryption and decryption to wav)

关于viterbi编码的，信道编码相关程序，适用(viterbi_decoder2_p)
