Polynomial Manifold Interpolation for Direction Finding in the Presence of Mutual Coupling
IEEE Access, 2019 Direction-of-arrival (DOA) estimation in the presence of mutual coupling among the antennas is an important problem in direction finding systems. To address the mutual coupling issue, a polynomial manifold interpolation approach is proposed in this paper.

2D DOA estimation based on matrix method and joint diagonalization technique
Tongxin xuebao, 2013 When space phase factors are the same in one direction or two orthogonal directions,the convensional direction-of-arrival methods cannot estimate DOA effectly,resulting in performance degradation.Therefore,joint diagonalization technique was utilized to ...

Does Fit Always Fit? The Paradox of Brand–Cause Misfit and Authenticity
Psychology &Marketing, EarlyView.ABSTRACT Brand–cause research generally treats coherence between a brand and a social cause as a prerequisite for authenticity, leaving unexplained why some moderately misfitting initiatives are judged more authentic than expected. We develop a paradox‐based process account in which authenticity arises not only from coherence but also from consumers ...
