此程序用来一个BPSK的调制信号。程序后面都有详细的注解，帮助理解！(This program is used to a BPSK modulated signal. Procedures are followed with detailed comments, to help understand!)

用于统计任一英文文档中26个字母的统计频率，得到频率矩阵(Second, it fuses the features of the first singular value component and the second one, and then gets the complex feature vectors which reflect not only the statistic frequency but also the sequential structure of letters. In the end, the cosine similarity of texts is used to measure the similarity between the query and documents.)

LBP特征提取的MATLAB实现，其getmapping.m定义了lbp三种不同的模式，而lbp.m则是lbp的实现，当然它只是简单的整幅图像的lbp变换（没有分区域），其中很巧妙地运用了整体移动的方法计算lbp值。(LBP feature extraction MATLAB, which getmapping.m defines lbp three different modes, while lbp.m is lbp realize, of course, it simply lbp transform the whole image (no sub-region), which is very clever use of the method of calculating the overall mobile lbp value.)
