    Abstract
  • To increase the convergence rate of the improved normalized subband adaptive filter, a simple but effective method is presented to change the reusing order of coefficient vectors of the adaptive filter. At the beginning of adaptation the algorithm just uses its current coefficient vector to update the adaptive filter to maintain fast convergence rate, while in steady state it employs several most recent coefficient vectors to update the adaptive filter to reduce misalignment. Simulation results show that the proposed algorithm can obtain both fast convergence rate and small steady-state misalignment.
