Description/Abstract

In this paper, we propose a novel subband adaptive broadband beamforming architecture based on the generalised sidelobe canceller (GSC), in which we decompose each of the tapped delay-line signals feeding the adaptive part of GSC and the reference signal into subbands and perform adaptive minimisation of the mean squared error in each subband. Besides its lower computational complexity, this new subband adaptive GSC outperforms its fullband counterpart in terms of both convergence speed and steady-state error. Simulations based on different kinds of blocking matrices with different orders of derivative constraints are presented to support these findings.
