Abstract: In this paper,the recurrence formulae for solving partitioning Toeplitz matrix equations are given,and are used in artificial model experiment. Experimental results show that multichannel deconvolution has advantage over single-channel deconvolution. In addition. we defined the meannign of multichannel minimum phase, and verified the definitive stability under one-step prediction case.

Key words: multichannel deconvolution, minimum phase, filter stability, partitioning Toeplitz matrix
