中文说明： 分析了该信号的时域、频域、倒谱，循环谱等,music高阶谱分析算法，实现串口的数据采集，基于matlab GUI界面设计,采用偏最小二乘法，用于特征降维，特征融合，相关分析等。
English Description：
The time domain, frequency domain, cepstrum and cyclic spectrum of the signal are analyzed. The music high-order spectrum analysis algorithm is used to realize the data acquisition of serial port. Based on Matlab GUI interface design, partial least squares method is used for feature dimension reduction, feature fusion and correlation analysis.
