Multi-rank adaptive beamforming
2005 (English)In: 2005 IEEE/SP 13th Workshop on Statistical Signal Processing: Bordeaux, France, 17 - 20 July 2005, Piscataway, NJ: IEEE Communications Society, 2005, 307-312 p.Conference paper (Refereed)
This paper presents a multi-rank generalization of the Capon beamformer to accommodate model mismatch in situations where the unknown signal of interest lies in a multidimensional subspace. By expanding the beamforming subspace robustness (or diversity) is achieved at the expense of resolution. The generalization involves solving a quadratically-constrained quadratic minimization problem, and designing a constraint matrix. Three strategies for designing this constraint matrix are discussed. Simulation examples are presented to demonstrate the performance of the multi-rank Capon beamformer.
