共空间算法 (CSP)是找到最优空间投影使两类信号的功率最大，因此它能估计出两个空间滤波器来提取任务相关信号成分，并且同时去除任务不相关成分和噪声。此程序可能会有一点小问题，仅供大家参考学习。(The Common Space Algorithm (CSP) finds the optimal spatial projection to maximize the power of the two types of signals, so it can estimate two spatial filters to extract the task-related signal components and simultaneously remove the task irrelevant components and noise. This procedure may be a little problem, only for everyone to learn.)
