Abstract

In this paper, we propose an equivalent model for subband adaptive systems, in order to analyze the performance of the system. Using the proposed model, we obtain a new interpretation of the system, and show theoretical equations of the optimum adaptive digital filter (ADF) coefficients and the least mean squared error (LMSE). From these equations, we also derive the theoretical values of the optimum ADF coefficients and the LMSE. Comparing them with results of computer simulations without the model, we can see agreements of the theoretical values and the simulation results
