This paper presents a new adaptive algorithm for the linearly constrained minimum variance (LCMV) beamformer design. We incorporate the set-membership filtering (SMF) mechanism into the reduced-rank joint iterative optimization (JIO) scheme to develop a constrained recursive least squares (RLS) based algorithm called JIO-SM-RLS. The proposed algorithm inherits the positive features of reduced-rank...
This paper presents a new direction-of-arrival (DOA) estimation algorithm, where DOA estimation is realized in the framework of beamforming by introducing a new optimization problem. The new optimization problem aims to minimize the variance of the array output subject to retaining the output power at the look direction and precluding a trivial solution. The proposed algorithm is equivalent to the...
