提出了一种空间总集全局寻优的求逆方式，改进了在脑电逆问题的研究中，传统的时空全局寻优求逆及静态求边方式的不足。为了能够利用单次或少量几次刺激对脑电诱发响应信号进行定位求逆，提出了空间因子求逆方式及相关噪声抵消法，有效地消除了脑电诱发响应中强背景噪声的影响。仿真研究表明，利用这些方法，在信噪比为－１０ ｄＢ的情况下，仍能对诱发响应信号进行准确的定位和提取。
In this paper, a global inversion method of global optimization is proposed, which improves the shortcoming of the traditional global optimization inversions and static ways in the study of the inverse problem of EEG. In order to locate and invert EEG-evoked response signals with single or few stimuli, a space factor inversion method and a correlation noise cancellation method are proposed, which effectively eliminate the influence of strong background noise in EEG-induced responses. Simulation results show that these methods can still accurately locate and extract the induced response signal with SNR of -10 dB.
