语音处理，改变声调、语速等，matlab代码

这是一个完整的OFDM通信系统仿真代码。包括信源编码信源调制，信道编码，信道估计，峰均抑制比等。实际程序可用直接运行。(This is a complete OFDM communication system simulation code. Including the source modulation source coding, channel coding, channel estimation, peak to average ratio suppression. The actual procedure can be run directly.)

并联有源电力滤波器（APF）基于空间矢量的滞环控制(Shunt active power filter (APF) based on space vector control hysteresis)

C# 写的NetRemoting通信例子 双向通信(NetRemoting Communication Example Written in C# Two-way communication)

uwb仿真，上传到上来给大家一个参考，希望能有帮助(UWB simulation, upload onto a reference to the U.S., hoping to have help)

信息经格雷码映射，进行QPSK调制并通过AWGN信道发射，在接收端进行QPSK解调，并统计误符号率和误码率。(Information on the Gray code mapping, QPSK modulation and emission through the AWGN channel, QPSK demodulator at the receiving end, and the statistical symbol error rate and bit error rate.)

实现了polar在BEC信道下的编译码，画出了误码率图像(The encoding and decoding of polar in BEC channel is realized, and the bit error rate image is drawn.)

基于matlab实现的循环谱估计算法，可以对具有循环平稳特点的信号进行参数估计(Matlab-based spectral estimation algorithm to achieve the cycle, you can have the characteristics of the signal cyclostationary parameter estimation)

cdma系统，发射机采用直接扩频序列后发射，接收机采用MMSE接收机(cdma systems, the transmitter after the launch of direct sequence spread spectrum receiver using MMSE Receiver)

说明：  这是自由空间路径损耗的代码。里面有多个m文件(This is the code of path loss in free space. There are multiple M files in it.)

说明：  详尽描述了3GPP LTE环境中小区间资源分配仿真的全过程，有蜂窝小区的模拟方法和资源调度的算法，还有性能仿真的曲线图(3GPP LTE detailed description of the allocation of resources between the environment small and medium-sized simulation of the entire process, and the simulation of Cellular and resource scheduling algorithm, as well as the curve of performance simulation)
