| Abstract: | A robust sub-array asynchronous RLS algorithm based on the M-estimate (named Sub-Array robust M-estimate RLS: MSARLS) is proposed and used in the beamforming of adaptive arrays. The new algorithm integrated the robust M-estimate RLS and asynchronous sub-array RLS to improve the performance of RLS algorithm in beamforming. Not only the anti-interference performance was enhanced, but the calculation amount was also decreased. The theoretical analysis of calculation amount and simulation results of the algorithm performance is described in this paper. |
