说明：  按照给定指标采用模拟巴特沃斯低通滤波器去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 (Indicators in accordance with a given analog Butterworth low-pass filter to approximate the ideal analog low-pass filter, and then through the bilinear transformation method of digitizing analog filters, digital filters have been)

cvlib_mex为封装了openCV重要函数的库，matlab可以直接调用文件从而运行openCV函数。压缩包中已包含cvlib_mex.mexw64文件，可以直接使用。PS:mexw64适用于windows下的64位matlab。(cvlib_mex important function to encapsulate the openCV library, archive already contains cvlib_mex.mexw64 files can be used directly. PS: mexw64 applicable under windows 64 matlab.)

chirp信号matlab源代码程序，及信号的时域和频域压缩代码(time domain and frequency domain chirp signal matlab source code program, and signal compression code)

实现扩频CDMA系统的仿真，并实现不同用户数下误码率的输出(can present the simulation of dsCDMA)

CUED系统识别工具箱，包括： 1 Subspace identification of linear systems. 2 Subspace identification of bilinear systems(CUED System Identification Toolbox: 1 Subspace identification of linear systems. 2 Subspace identification of bilinear systems)

这是一个matlab编写的电离层误差图的程序。里边分别利用广播星历和模型修正进行了编程。(It is written in a matlab program ionospheric error plots. Inside were using broadcast ephemeris and model updating for the programming.)

说明：  GAPSO算法是一种先进的遗传粒子群算法，广泛应用于电力系统的低频振荡的控制研究。中。(无)

说明：  这是用matla本作的对雷达系统通信的源程序，对软件硬件开发者都有极大帮助(This is used for matla the radar system on the source of communication for software and hardware developers are extremely helpful)

信号与系统，信号与系统课设的信号加入噪声以及滤波(Signals and Systems, Signals and Systems course set signal to noise and filtering)
