CONJUGATE GRADIENT TECHNIQUES FOR MULTICHANNEL ADAPTIVE FILTERING

Lino García Morales, Fernando Juan Berenguer Císcar

Abstract

The conjugate gradient is the most popular optimization method for solving large systems of linear equations. In a system identification problem, for example, where very large impulse response is involved, it is necessary to apply a particular strategy which diminishes the delay, while improving the convergence time. In this paper we propose a new scheme which combines frequency-domain adaptive filtering with a conjugate gradient technique in order to solve a high order multichannel adaptive filter, while being delayless and guaranteeing a very short convergence time.
