摘要
脑电 ( Electroencephalographic,EEG)视觉诱发电位 ( Visual Evoked Potential,VEP)的提取在生物医学信号处理领域近年来是一项备受关注的研究问题 .本文提出的一种基于独立分量分析法 ( Independent Component Analysis,ICA)单次提取多导脑电信号 ,其与叠加平均法相比 。
Single trial estimation of visual evoked potential has interested many researchers in the field of biomedical signal processing over recent years.In this paper a method based on the independent component analysis(ICA)was proposed for single trial estimation of multi channel visual evoked potential which can obtain results 200 times clearer than conventional coherent averaging.
