This code may be useful for sensing spectrum in cognitive radio

二进制通信系统的进行蒙特卡罗仿真程序，以正交信号为基础。当均值分别等于０，０.１，１.０，２．０时完成１００００个比特的仿真并求出误差概率。绘出理论误码率和蒙特拉罗仿真的差错率并进行比较这俩个结果，并绘出每个均值情况下判决器的１０００个接受信噪比抽样(Binary communication systems to carry out Monte-Carlo simulation procedures to orthogonal signal basis. When the mean, respectively, equivalent to 10,000 completed 0,0.1,1.0,2.0 bit error probability simulation and obtained. Mapping theory and蒙特拉罗BER simulation这俩error rate and compare results, and the mean circumstances of each mapped)

The following Matlab scripts are used to plot the basic torque slip curves with changing input voltage, and input frequency.

语音基本间隙检测算法，voice activity detection(basic voice Gap Detection Algorithm, voice activity detection)

直接序列扩频 实现扩频、解扩还有。MATLAB实现环境。其中解调用的是BPSK。(Spread Spectrum Direct Sequence Spread Spectrum, despreading there. MATLAB implementation environment. One solution is called BPSK.)

实现haffuman编码的功能，可以正确运行仿真并实现正常的输出(Encoding functions to achieve haffuman)
