PROBLEM TO BE SOLVED: To estimate an unknown system at high speed even in the case that the unknown system has an echo characteristic and a signal to be sent exhibits a chromatic component. SOLUTION: A multi-channel system identification apparatus updates an FIR filter simulating impulse responses from input channels to output channels, respectively, according to an adaptive algorithm. In the updating, a vector reducing a correlation component of a reference signal is used. COPYRIGHT: (C)2008,JPO&INPIT
