说明：  能量循环检测程序，matlab仿真，内有程序和代码说明。(Energy cycle test procedures，matlab simulink)

毕业设计。用MATLAB实现BPSK编程。(Graduation project. Using MATLAB for BPSK.)

说明：  仿真一个QPSK调制信号通过一个平坦瑞利衰落的AWGN信道的误码率(simulate the BER of a QPSK modulated siganal using an AWGN channel with flat rayleigh fading)

说明：  画n角星,其中n为大于5的奇数(偶数可以看成两个奇数角星的叠加) 比如6角星,可以看成两个三角星的叠加(Plotting and filling n-pointed star, in which n is an odd number greater than 5)

此源程序基于GPS快速捕获算法的研究，包含的了三种捕获方式的matlab实现(This source code based on the GPS fast acquisition algorithm research, including the three capture methods to achieve the MATLAB)

该程序设计了一种分数阶tid控制器，能有效弥补常规tid控制器所无法实现的目的，多两个可调参数就多了控制系数，功能更有效，性能更稳定。(The program design of a fractional tid controller can compensate for conventional tid controller can not achieve the purpose, more than two adjustable parameters, the more the control coefficient, more effective and more stable performance.)

一个navigation vieew的xcode手机程序可直接使用。 (A navigation vieew the xcode phone program can be used directly.)

无循环实现S变换，S变换在信号分析中十分有效，它的时空分辨率要高于小波变换，效率很高的程序(This code computes the Stockwell transform (S-Transform) of a one dimensional series without for loop, thereby making it computationally fast and simple. S-Transform was proposed in 1996. A nice tutorial on S-Transform can be found here: djj.ee.ntu.edu.tw/S_Transform.pdf‎ )

Short Term Energy is important for filtering a signal. With Short Term Energy, we can get voiced and unvoiced.
