Abstract :
In this paper we develop theoretical equations for calculating the reconstructed mean-square error (MSE), E[|e2|] for the subband adaptive filter system under zero mean, unit variance white Gaussian input. These systems are seeing increased use in acoustic echo cancellation applications and by performing the calculations, we are potentially able to evaluate and compare performance for various design parameters and various modifications to the basic design
