Abstract :
This paper describes system identification using a subband adaptive digital filter (ADF) valuable for a wide band system with very higher order impulse response. To analyze the system identification problem equivalent models are introduced and analyzed. The relationships between impulse response of the unknown system and coefficients of subband ADFs in the steady state are shown. We discuss the performance of the subband ADF, focusing on filter bank characteristics. We also discuss the simulation results of the subband ADF
