| Description | in Proc. IEEE Workshop on Stat. Sig. Proc 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 the GSC and the reference signal into subbands and perform adaptive minimisation of the mean squared error in each subband independently. Besides its lower computational complexity, this new subband adaptive GSC outperforms its fullband counterpart in terms of convergence speed because of its prewhitening eect. Simulations based on dierent kinds of blocking matrices with dierent orders of derivative constraints are presented to support these ndings. 1. |
