一个可用的信号特征提取、信号消噪，matlab编写

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

本程序是使用MATLAB编写的，包括ASK、BPSK、EPSK、FSK、OOK、QPSK等仿真。(this procedure is the use of MATLAB, including ASK, BPSK, EPSK, FSK, OOK, QPSK, and other simulation.)

因子图和和积算法的matlab实现，给需要的人用，谢谢你的宝贵建议(factor graph and sum-product algorithm )

说明：  利用winpcap编写的，直接从链路层收取数据帧的小程序，希望能有点用处。(use winpcap prepared directly from the data link layer frame collection of small procedures in the hope that this will usefulness.)
