Abstract

Abstract

This paper presents a ESPRIT-based algorithm to estimate carrier frequencies of independent spatial signals with no geometric constraints on the array. After mapping the element space data into DFT space, the frequency vector is extracted which is independent of array information, and then beamspace ESPRIT is used to estimate the spatial signals frequencies via an indirect ESPRIT method. The simulation results demonstrate our algorithm to be of high-resolution and high-precision with arbitrary array geometry.
