在MATLAB中通过四阶龙格库塔法，计算时滞微分方程,(In MATLAB by fourth-order Runge-Kutta method to calculate the delay differential equation)

基于matlba的常见信号设计，全部都经过实验验证，可作为子函数使用(Common Signal Design matlba based, all through experimental verification, use as Functions)

目的：实现多gui间的通信。 1. 由gui1打开gui2，并从gui2读取数据画图； 2. 数据包的传递：在gui1定义一个数据包，包括字符串，数据，把数据包传递给gui2并由其更新，gui2更新好的数据在传回gui1并显示出来。（注：程序中加黑划线部分为实现预期功能的要点） (Purpose: communication gui. Method: 1. Opened by gui1 gui2, and to read data from gui2 drawing (2) the transfer of the packet: a packet defined in gui1, including strings, data packets passed to gui2 updated by gui2 the updated data in the returned gui1 and displayed. (Note: the program plus the the black underlined part to achieve the desired functionality of the points))

输入一个脉冲响应文件，可以测得房间混响时间T20 T30(Enter a pulse response file, can measure the room reverberation time T20 T30)

在无线通信体系中,由于开放的通信信道条件,卫星通信系统中通信链路容易受到平均大气条件的影响,尤其是采用Ka波段的高频信号的系统,容易受到降雨造成的雨衰影响,严重影响了系统的有效性和可靠性。(In a wireless communication system, the communication channel open, average atmospheric conditions vulnerable to the communication link in satellite communication system, especially the system of high frequency signal using Ka band, vulnerable to the influence of rain attenuation caused by rainfall, seriously affect the validity and reliability of the system. In digital systems, channel coding is often used to improve reliability, while modulation is used to ensure effectiveness. Low order modulation and large redundancy coding are adopted to improve the reliability.)
