摘　　要：给出了一种基于Jade的EP信号少次提取方法,实验表明,这种方法能够有效地提取出混合在噪声中的2个周期的EP信号,并与Fast ICA算法在数据分析,相关系数矩阵分析,算法执行时间分析这3个方面做了比较.通过数据和实验发现,Jade算法能有效的少次提取EP信号,且提取效果好于Fast ICA算法.A few-trials extraction method of EP signal is presented based on Jade. Experiments show that this method can effectively extract EP signal of two cycles which is mixed in the noise. Compared with Fast ICA al- gorithm in data analysis, correlation coefficient matrix analysis, algorithm execution time analysis, it is found that the Jade algorithm can effectively extract the EP signals, and the extract is better than Fast ICA algorithm.
