Description/Abstract
In this paper, we compare low cost implementations of wideband adaptive beamformers utilising the generalised sidelobe canceller (GSC) in combination with the least-mean squares algorithms. DFT based techniques suffer from unjustified narrowband assumptions. We therefore derive and investigate an overlap-save implementation of the GSC, which offers a steady state suppression of jammers equivalent to a time domain GSC but may be prone to slow convergence. Finally, subband techniques offer a more robust convergence trade-off for a somewhat higher computational cost. Analysis and simulation results revealing some of the algorithms' properties are presented.
