以下几个matlab程序对雷达常用的线性调频信号（lfm信号）进行脉冲压缩时的关键问题进行了仿真，其中包括旁瓣抑制影响（加窗与不加窗）、多卜勒频移影响，并对时域脉压与频域脉压结果进行了对比分析，供相关技术人员参考。(Matlab following procedures commonly used on the radar LFM signal (lfm signal) for pulse compression at the time of the key issues of simulation, including the impact of sidelobe suppression (plus a window with no window), the impact of Doppler frequency shift, time domain and frequency domain pulse pressure and pulse pressure results of comparative analysis of relevant technical personnel for reference.)

说明：  自编：张贤达《数字信号处理》习题4.26的MATLAB程序。加入了一个GUI界面。 在MATLAB下运行MDSP。 要求MATLAB7以上版本，否则GUI无法运行(self : Automation, "Digital Signal Processing" Exercise 4.26 MATLAB. Adding a GUI interface. MATLAB running MDSP. MATLAB7 version of the above requirements, otherwise unable to run GUI)

排队系统仿真,考虑一个排队系统，顾客到达后，若无空闲服务台则等待，否则接受服务后离开。仿真目的是统计服务台前的平均队长和服务台的忙闲程度。要求能利用离散事件系统仿真的方法对该系统进行仿真，系统的规则和参数自定。(queue up system simulation)

Least squares sinusoid fit algorithm described in IEEE Standard for Digitizing Waveform Recorders (IEEE Std 1057): Algorithm for three-parameter and four-parameter least squares fit to sinewave data using matrix operations. The algorithm is (in most cases) really quick. If the signal frequency is a guess, it has to be close to true frequency value. For further information, consult IEEE Std 1057 and/or IEEE Std 1241 documentation. Now also fits complex sinusoids i.e. phasors with noise and o
