基于能量检测的频谱感知.由于实际信道中的多径和阴影效应，单个认知用户频谱感知的性能受到影响，因此需要靠不同用户间的协同频谱感知来对抗多径和阴影效应。本设计要求在文中采用一种协作机制，即两用户进行协作频谱感知，提高主用户的检测率，减少检测时间，并且得到捷变增益。要求给出仿真结果。(spectrum sensing in cognitive radio based on energy detection.As the channels in diameter and shadow, not a single user spectrum of capabilities and therefore need different between a user to the spectrum is perceived as more and the effect. this design for the use of a coordination mechanism, the two users collaborate spectrum, the detection rate of increase and decrease the test of time and get a change requires immediate gain. some emulation. )

很不错的粒子滤波器入门程序，在一个外国网站下载的(Very good particle filter entry procedures, in a foreign Web site download)

将方波周期信号展开成傅里叶级数并生成3次，5次，8次，10次谐波(Expand the square wave into a Fourier series of periodic signal and generates 3 times, 5 times, 8 times, 10 times harmonic)

说明：  这些程序是MIT学生学习Matlab时的教学程序，能面还有个pdf文档附有每个程序所实现的功能(This is the teaching codes at MIT for learning Matlab. hope it is helpful for you.)

V_RESAMPLE is a Matlab function implementing nonuniform data sampling. It resamples the input data at the specified, continuously variable sampling rate, which may be locally higher or lower w.r.t. the original rate. Aliasing terms are taken care of by appropriate smoothing.

说明：  当用户已知系统的输入和输出时，该程序可用来估计系统的参数！(Known system inputs and outputs, it is estimated the parameters of the system!)
