Performance comparison of the sparse and non-sparse robust FSBBs with comparable amount of active tap weights. For the sparse FSBB, the number of active weights is 738; while for the non-sparse FSBB, the number of active weights is 750. The steering direction ϕ d =60°. Average of 100 Monte Carlo trials. a Array response of the sparse FSBB. b Array response of the non-sparse FSBB. c Side view of a. d Side view of b. e PRV of the sparse FSBB. f PRV of the non-sparse FSBB. g Side view of e. h Side view of f
