从独立分量分析(ICA)的原理和算法入手,用傅立叶和ICA对实际测得的地震灾害救助系统中的声波/振动信号进行分离。从分离的结果看,ICA在复杂信号的分离中更具优越性。
Starting from the principle and algorithm of Independent Component Analysis (ICA), the acoustic / vibration signals in the actually measured earthquake disaster rescue system are separated by Fourier and ICA. From the results of the separation, ICA is more superior in the separation of complex signals.
