说明：  功率谱估计编程，可以进行时域频域的转换，并提取频率、振幅、功率谱密度等相关参数(The power spectrum estimation program can transform the time domain and frequency domain and extract the related parameters such as frequency, amplitude and power spectrum density)

设计一个数字FIR低通滤波器，其技术指标如下： Wp=0.2pi Rp=0.25Db Ws=0.3pi As=50db 试写出MATLAB设计的源程序。(Design a digital FIR low-pass filter, the technical indicators are as follows: Wp = 0.2pi Rp = 0.25Db Ws = 0.3pi As = 50db test designed MATLAB source code to write.)

说明：  思源科技出版 matlab基础与提高 7-8章 源代码(Springsoft Publishing matlab base and improve the source code of Chapter 7-8)

8PSK传输系统，包括调制解调和高斯信道(8PSK transmission system, including the modem and Gaussian Channel)

这是一个以惯性系为中间参考系的双矢量粗对准方法(This is an inertial frame coarse alignment method for the intermediate reference system double vector)

Modern wireless device have sleep mode which greatly reduce the duty cycle of the power supply.Consider the effect of different duty cycles and transmit times to see the wide range of battery lifetimes one may expect before recharging. results is being plotted of battery lifetime as a function of the duty cycles & duration of the wake up mode.

说明：  Matlab控制系统高级讲义以及课件中涉及到的算法的源程序，对matlab的进一步学习很有帮助，学控制的应该看看！(Matlab Control System courseware senior notes, as well as involved in the source algorithm on matlab helpful for further study, learning control should look at!)
