bpsk系统用matlab实现仿真，可以帮助大家更容易理解他的运行过程(BPSK systems realize matlab simulation, can help everyone more easily understand the operation of the process)

Matlab code which can be used for watermarking by using wavelat

运用此程序来去除光谱中的宇宙射线。。。。。。。。。。。。。。(use this promgram to denoise ray from unniversal.)

说明：  实现基频提取的RAPT算法（一种鲁棒性的基频提取算法）。输入文件为wav波形文件。(A Robust Algorithm for Pitch Tracking (RAPT))

自适应型广义形态滤波滤波器的源代码（内含腐蚀、膨胀、开闭运算、snr等代码），仅供参考(The source code of the adaptive generalized morphological filter filter (containing corrosion, expansion, opening and closing op, snr, and other code), for reference only )

这里用模糊函数对Barke进行分析，研究其时间和频率的 分辨率。(barker )

this simulation shows the implementation of the Induction machine and use of space vector triggering techniques..

正交频分复用其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。(Orthogonal Frequency Division Multiplexing)

部分MATLAB仿真，优化覆盖，完成了一些，希望对大家有帮助(Part of the MATLAB simulation, optimization of coverage, completed some, we want to help)
