Blind signal separation for coprime planar arrays: An improved coupled trilinear decomposition method

ETRI Journal, 2023
In this study, the problem of blind signal separation for coprime planar arrays is investigated. For coprime planar arrays comprising two uniform rectangular subarrays, we link the signal separation to the tensor-based model called coupled canonical ...

DOA Estimation of Coherent Signals on Coprime Arrays Exploiting Fourth-Order Cumulants. [PDF]

Sensors (Basel), 2017
This paper considers the problem of direction-of-arrival (DOA) estimation of coherent signals on passive coprime arrays, where we resort to the fourth-order cumulants of the received signal to explore more information. A fourth-order cumulant matrix (FCM)
