Abstract :
A novel robust beamforming scheme for the processing of coherent signals in a multipath environment is proposed, where the worst-case performance optimization and the soft response constraint are combined together to suppress the multipath signals as well as the uncorrelated interferences. The proposed scheme is also robust against the direction-of-arrival (DOA) estimation errors. Simulation results verify its effectiveness.
