摘要：
A time domain recursive algorithm for multichannel inverse filter design in sound reproduction systems is presented. The method exploits the non symmetric toeplitz-block structure of the actual multichannel system matrix that is used to specify the electroacoustic transmission paths. The result is a matrix of causal finite impulse response filters which best approximate a given time domain response in the least squares sense. The method presents low memory and computational requirements and its time updating properties make it suitable for real time applications in non stationary environments. A cross talk cancellation experiment is presented which illustrates the properties of the algorithm.
