BPSK-viterbi
基于维特比译码算法的BPSK解调方式，survivor_state是一个矩阵，它显示了通过网格的最优路径，这个矩阵通过一个单独的函数metric(x,y)给出，这个算法既能用于硬判决译码也能用于软判决译码。
(BPSK demodulation method based on viterbi decoding algorithm, survivor_state is a matrix, the optimal path of it shows through the grid, the metric matrix through a separate function (x, y), the algorithm can not only used for decoding hard decision can also be used to the soft decision decoding.

轴承信号分析
共振解调的过程如下：首先对采集到的信号进行傅里叶变换，然后利用传感器自身的谐振频率进行分析，对滤波后的信号进行包络，包络以后去除了高频部分，得到包络信号，再对改进的包络信号进一步进行低通滤波，最后对最终得到的信号进行傅立叶变换求其频谱图。共振解调的原理及其过程可以用图2 来进行表述。(The process of resonance demodulation is as follows: First, Fourier transform is performed on the collected signal, and then the resonance frequency of the sensor is used for analysis. The filtered signal is enveloped, and the high frequency part is removed after enveloping to obtain an envelope. The signal is further subjected to low-pass filtering on the improved envelope signal. Finally, the spectrum of the resulting signal is Fourier-transformed. The principle of resonant demodulation and its process can be expressed in Figure 2.)
