In this paper, we develop a new approach to the robust beamforming for general-rank signal models. Our method is based on the worst-case performance optimization using a semi-definite constraint on the mismatched signal covariance matrix. The resulting robust adaptive beamforming problem is solved using iterative semi-definite programming (SDP) with a guarantee of convergence. The performance improvement...
This paper presents efficient algorithms for optimal and suboptimal unconditional maximum likelihood (UML) directions-of-arrival (DOA) finding. In the conventional UML formulation an important condition is missing. That is the non-negative definiteness of the covariance matrix of signal components. Because of the lack of the important condition, inadequate global solution appears in the solution space...
