基于EEMD的地声信号单通道盲源分离算法
The single channel seismic-acoustic signal blind-source separation method based on EEMD
摘要
Abstract
With only a single observing channel, the blind source separation methods based on matrix calculating do not work. To deal with this problem, a single channel blind-source separation method for seismic-acoustic signal processing was presented. First, the observing signal was decomposed into intrinsic mode matrix by ensemble empirical mode decomposition, transforming the single channel underdetermined problem into the multi-channel positive definite problem. Then the input matrix for blind source separation was obtained. Finally, the source was estimated by the blind source separation method. The simulation results show that this method can separate the source signal from broad frequency and impulsive noise, and works well when the frequencies of different source signals overlap. Experimental results show that the signal-to-noise ratio can also be improved for seismic-acoustic background noise. It proves that this method is effective for processing seismic-acoustic signal.关键词
