摘要/Abstract

摘要： 就多维最小平方预测准测,推导了一种分块Toeplitzt矩阵方程组求解的递推公式,并对人工模型进行了实验,实验结果表明采用多道处理反褶积优于单道结果。文中还给出了多道最小相位的定义,并给出了在一步预测下多维反褶积算子确定性稳定的结论。

关键词: 多道反褶积, 最小相位, 滤波器稳定性, 分块Toeplitz矩阵

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
