摘　　要：基于ＡＲＭＡ 新息模型和Ｗｉｅｎｅｒ状态估值器，提出多通道Ｗｉｅｎｅｒ去卷滤波器设计的一种新的时域方法，给出了渐近稳定的递推Ｗｉｅｎｅｒ去卷滤波器，可统一处理去卷滤波、平滑和预报问题。同频域上的多项式方法相比，避免了求解Ｄｉｏｐｈａｎｔｉｎｅ方程，且便于实时应用。Based on the autoregressive moving average (ARMA) innovation model and Wiener state estimators, a new time-domain approach to the multichannel Wiener deconvolution filter design, is presented. Asymptotically stable recursive Wiener deconvolution filters are given, which can handle the deconvolution filtering, smoothing and prediction problems in a unified framework. Compared with the polynomial approaches in the frequency-domain, the solution of the Diophantine equations is avoided. The new approach is suitable for real time applications. A simulation example shows its effectiveness.
