Abstract
In this paper, two robust presteered broadband (PB) beamformers are developed using worst-case designs. The proposed techniques are shown to enjoy a reduced computational complexity and/or significant performance improvements as compared to the existing robust wideband beamforming techniques in scenarios with array response errors.
