摘要
Abstract
In order to eliminate aliasing noise signal of gastric motility impedance signals, using independent component analysis of the redundancy reduction features, a new method of gastric motility impedance signals denoise is proposed. Construction of virtual noise channel used empirical mode decomposition, the one-dimensional original gastric motility impedance signal is extended to multi-dimensional observation signals,and it is implemented blind separate by FastlCA algorithm. Simulation experimental results show that the denoise method can effectively eliminate the noise of gastric motility impedance signal. The method does not require a large number of observation samples, which can achieve denoise of a single observed sample by Independent Component Analysis(ICA).关键词
