采用Log-BP算法的LDPC码译码仿真程序,给出了不同信噪比下误码率和误包率的统计图,用matlab和Cc-mex程()

实现共振峰检测的MATLAb程序：分帧加窗；|FFT|；log；IFFT；log；平滑处理(MATLAb program for realization of resonance peak detection Frame windowing; |FFT|; log; IFFT; log; smoothing processing)

基于MATLAB使用高斯拉普拉斯算子（log）进行边缘检测将图像灰度化再提取边缘(edge detection using log, we can extract the edge of the image(transfer the image to gray image ))
