说明：  基于置信传播算法和Viterbi检测的ISI信道估计，比较两种算法的性能(ISI channel is estimated based on the belief propagation algorithm and Viterbi detection, compare the performance of the algorithm)

this program is GOP. GOP is group of frame descriptor. this descriptor is define a group of picture based on Scalable Color Descriptor (SCD)

文件夹LSB中是空域LSB算法程序，文件夹COX中是Cox算法主要程序，文件夹DCT中是频域加在中频的算法的程序。 步骤：把LSB，COX，DCT三个文件夹考在MATLAB目录下； 运行lsb_embed,programme,dct2_embed_mod即可。其中PSNR.m是计算峰值信噪比程序；attact.m & robust.m是攻击程序。(Content: folder LSB of spatial LSB algorithm program, folder COX Cox algorithm is the main program folder DCT frequency domain is added to the IF algorithm program. Steps: the LSB COX DCT three files folder test in the MATLAB directory run lsb_embed program, dct2_embed_mod can. The which PSNR.m calculate the peak signal to noise ratio procedures attact.m & robust.m exploit.)

基于QR分解的岭回归函数，这个函数是非的有用是已经证明过的准确程序( center input and output, so we can estimate w0 separately since we don t want to shrink w0 )

说明：  采用gardner法，实现定时定时同步，做这个已经有一段时间了(By gardner method, to achieve timing synchronization time, to do this has been for some time)
