胡广书数字信号处理的MATLAB程序，函数按章节号命名(HU Guang-book digital signal processing of the MATLAB program)

无线传感器高效能量路由算法——heed算法(Energy efficient routing algorithm for wireless sensor- heed algorithm)

多用户检测器的性能分析和仿真研究，有详细的源代码，希望各位有用(Multi-user detector performance comparison analysis of simulation studies, the main simulation file has detailed instructions)

用matlab写的图像离散余弦变换域的水印嵌入与提取以及攻击测试代码，稍加修改就可以移植到自己的程序中，很有用哦(Matlab write images using discrete cosine transform domain watermark embedding and extraction as well as attacks on the test code, slightly modified can be transplanted to their own program, very useful Oh)

应用FFT方法计算时间序列平均周期的源码。不是很复杂，不过效果比较好。可供参考(Application of FFT calculated the average cycle time of the source sequence. Not very complicated, but the effect is better. For reference)

说明：  是用matlab编译的wiener滤波器，实现噪声的消除和语音质量的提高(Is compiled matlab wiener filter, to achieve noise cancellation and voice quality improvement)

The ALOHA protocol was one of the oldest random access protocols, invented by Norm Abramson in 1969. The first wireless network, implementing packet switching over radio, used the pure ALOHA variation, have initially established in Hawaii.

this is a FDTD with PML ABC for infinite linear source...

filter details with despription........

此程序用于去噪声并进行分数阶傅里叶变换求出最优阶。(This procedure used to noise and fractional Fourier transform to find the optimal order.)
