说明：  本程序 包含两个函数 实现了 快速的沃尔什变换(This program contains two functions to achieve fast Walsh transform)

its utlizieses the techniques in removal of noise

这里提供了两个消除趋势相的matlab程序 在故障诊断中 要对信号进行频谱分析 而在频谱分析前要消除趋势相 这样得到的频谱 能更好的反映故障 有利于进一步诊断(Here are two trends in the elimination phase of the matlab program in fault diagnosis to the signal spectrum analysis and spectrum analysis in the former to eliminate the tendency of such spectrum can be better reflected further in favor of fault diagnosis)

matlab论文，对于一些人可能有用的。第一次上传，不是很精通。呵呵(matlab papers may be useful for some people. The first upload is not very proficient. Hehe)

matlab程序的一些算法，需要的同学可以直接引用(Matlab procedures some algorithm, the needy students can directly apply)

快速PCA算法，用于对大规模数据进行PCA降维，节省时间(fastPCA for large scale data which can save proceeding timE)

射频方面的资料，里面有详细的M文件，希望对大家有用。(Radio frequency information, there are detailed paper M, in the hope that useful to everyone.)

irst, let s create a simple vector with 9 elements called a.

根据FSK调制原理 在二进制频移键控中，幅度恒定不变的载波信号的频率随着输入码流的变化而切换（称为高音和低音，代表二进制的1和0）。来做实验 (According to the principle of FSK modulation in the binary frequency shift keying, the frequency of the carrier signal amplitude constant with the change of the input stream is switched (called treble and bass, representing a binary 1 and 0).
