Low complexity sparse beamspace DOA estimation via single measurement vectors for uniform circular array

Abstract In this paper, we present a low complexity sparse beamspace direction-of-arrival (DOA) estimation method for uniform circular array (UCA). In the proposed method, we firstly use the beamspace transformation (BT) to transform the signal model of UCA in element-space domain to that of virtual...
