Direct inverse identification method and device for multi-input multi-output system, program and storage medium, multi-input multi-output reverse filter device and method

摘要

To identify an unknown multiple input multiple output system inverse system/inverse filter directly from I/O data.SOLUTION: An inverse filter device using a multiple input multiple output system as a transmission system includes first through (M×M)th inverse filters G^-G^(M is an integer of 2 or more), and first through M-th output parts U-U, where the inverse filters G^, ..., G^input sources S(i=1, ..., M), and the output part Uoutputs the outputs from the inverse filters G^, ..., G^while adding. A processing section identifies the estimates g^of respective filter factors of the inverse filters G^(i,j=1, ..., M) directly from the I/O measurement values of the multiple input multiple output system, by executing the processing of the estimates g^of respective filter factors by a direct reverse identification method.SELECTED DRAWING: Figure 7
