Algorithm 1
Design of the FIR filters, the spatial weights, and the time windows.
Input: and : the sets of observed signals. | Parameters: : the number of FIR filters, : the filter order, | : the set of the candidates for the time window. | Output: : the spatial weights, : the vectors of | FIR filter coefficients, : the time window. | for do | Initialize and . | Set the index of iteration as . | repeat | . | Update by solving (11). | Update by solving (13). | Update by solving (19). | Calculate cost, from the cost function, . | until is sufficiently small. | end for |
