Joint multidimensional optimization for blind DOA estimation of uniform circular arrays with unknown mutual coupling

Mutual coupling distorts the array manifold and can severely degrade direction-of-arrival (DOA) estimation by subspace-based methods. This paper develops a blind DOA-estimation framework for uniform circular arrays with unknown mutual coupling. By exploiting the complex symmetric circulant structure of the coupling mat...
