Abstract
Novel robust beamforming algorithms are proposed to avoid signal cancellation in a multipath environment. The robustness is achieved by forcing the array responses to the signal of interest and its multipath signals in the pre-estimated clusters to be no less than unity while minimising the output power. Since the array responses to all the multipath signals are constrained, they will not cancel the signal of interest completely as in the conventional adaptive beamforming methods. The effectiveness of the proposed algorithms is verified by computer simulations.
