中文说明：验证可用，包括回归分析和概率统计，结合PCA的尺度不变特征变换(SIFT)算法，主要是基于mtlab的程序，分析了该信号的时域、频域、倒谱，循环谱等,到达过程是的泊松过程。
English Description：
Validation available, including regression analysis and probability and statistics, combined with PCA scale invariant feature transform (SIFT) algorithm, is mainly based on MTLAB procedures, analysis the the signal in time domain and frequency domain, cepstrum, cyclic spectrum, the arrival process is Poisson process.
