说明：  认知无线电中关于频谱感知的一些小程序，希望对大家有所帮助！(Spectrum sensing in CR,I hope it s useful to some guy!)

matlab编写的迷宫图游戏，很经典的！( matlab prepared maze game, very classic! matlab prepared maze game, very classic!)

自己编的一个matlab 程序，先对图像进行加噪声，然后进行滤波，再进行边缘检测(Made themselves a matlab program, the first increase the image noise, and then filter, then the edge detection)

this is the source code for the radon transform. it is the c file. u have to save this file as c file and then compile it using mex compiler in matlab.

给出接收信号眼图及系统仿真误码率，一个很有用的程序，对于初学者具有参考意义，有小波分析的盲信号处理。( The received signal is given eye and BER simulation systems, A very useful program, For beginners with a reference value, There Wavelet Analysis Blind Signal Processing.)

说明：  观察高斯序列 的时域和幅频特性。 ①固定p=8，q分别等于2、4、8，观察它们的时域和幅频特性，了解当q取不同值时，对信号序列的时域和幅频特性的影响 ②固定q=8，p分别等于8、13、14，观察p变化对信号序列时域和幅频特性的影响，注意p等于多少时，会发生明显的泄露现象，混叠是否也随之出现？记录实验中观察到得现象，绘出相应的时域序列和幅频特性曲线(Observed Gaussian sequence in time domain and amplitude-frequency characteristics. ① fixed p = 8, q is equal to 2,4,8 respectively, to observe them in time domain and amplitude-frequency characteristics, to understand when the different values of q, the signal sequence in time domain and amplitude-frequency characteristics of ② fixed q = 8 , p is equal to 8,13,14 respectively, to observe the changes in the signal sequence p in time domain and amplitude-frequency characteristics, note that p is equal to the number when the apparent leakage phenomenon, aliasing is also gone? Records of the experiment was observed phenomenon, draw the corresponding time-domain sequence and amplitude-frequency characteristic curves)
