语音处理，改变声调、语速等，matlab代码

说明：  MSK信号的调制与解调，根据书上的代码进行了修改，非常详细(Modulation and demodulation of MSK signal)

用于通信方向中的信道估计，使用的语言是matlab(Used for channel estimation in the communication direction, the language used is matlab)

说明：  精心搜集的IQ解调方面的matlab程序和资料文档 非常好 快点下把(Carefully collected the IQ demodulation matlab program and data documentation is very good quickly download)

Random soource. This signal control is used for Random Source, Modulation, Antenna Slector modules

说明：  energy efficiency code for cognitive radio

用simulink中s函数实现离散系统传递函数(S function with simulink realization of discrete system transfer function)

本程序是写的是扩展高斯（EGF）滤波器，当两个输入为根号1/2的时候就是IOTA滤波器，用于通信系统发端的波形塑形(This function calculates a filter with egf characteristic)

说明：  最简单的收发程序，可以用于超宽带测距，信道通信等等(The simplest transceiver program can be used in UWB ranging, channel communication and so on)

说明：  psk调制,在matlab命令区输入bpskdigital[1 0 1 1 0 0 1 0],1]按运行,即可看到调制波(Psk modulation, input bpskdigital [1 0 1 0 0 0] in the matlab command area, 1] press operation, you can see the modulation wave)

VB的CRC16校验源码，调试成功，程序简单。(The CRC16 checksum VB source code, debugging successful, the program simple.)
