Recursive algorithms of adaptive processing in the case of the central symmetry of the space-time reception channels
Abstract
The paper examines regularized recursive algorithms for the estimation of correlation matrices of external noise and corresponding inverse matrices in systems with central symmetry of the space and/or time reception channels. It is shown that adaptive-processing algorithms based on these recursive algorithms provide a speed of response for the system that is twice that provided by the 'fastest' existing algorithms for systems with an arbitrary arrangement of reception channels. The computational complexity of the estimation algorithms is considered, and a modification with a reduced level of complexity is proposed.
