摘要 脑电 (Electroencephalography ,EEG)视觉诱发电位 (VisualEvokedPotential,VEP)的单次提取是当前生物医学信号处理领域的一个研究热点。提出一种基于独立分量分析 (IndependentComponentAnalysis,ICA)的多道脑电信号VEP单次提取方法 ,与多次叠加求平均的方法相比较 ,可以得到令人满意的结果。 Single-trial estimation of visual evoked potential is the very interesting field in biomedical signal processing at present. A method based on the independent component analysis(ICA) was proposed for single-trial estimation of multi-channel Visual Evoked Potential(VEP). It achieved a result which was clearer than that obtained by 200 times conventional coherent averaging.
