各位高手,我是做STFICA的,前两天看了篇文章上说的在进行STFICA时必须预白化,要求的方法是多信道前向线性预测的最小二乘解法出系数做预白化(The coefficients for the th row of the transfer function matrices are calculated by solving a least-squares multichannel forward linear prediction task, e.g.,by minimizing the output power of the th output signal.),这一方法怎么用MATLAB编程啊,想了好长时间没头绪,请各位高手指点,谢谢!
