Abstract

This paper presents a subspace-based algorithm for the simultaneous estimation of angle of arrivals (AOAs) and angle of departures (AODs) from an estimated spatial signature at the receive antenna array. The algorithm exploits a 2-D unitary ESPRIT-like technique to separate and estimate the phase shifts due to the AOAs and AODs with automatic pairing of the two parameter sets. The Cramer-Rao lower bound (CRLB) on the AOAs and AODs estimates is provided. The performance of the algorithm is illustrated based on the computer simulation. It shows that the proposed algorithm is an efficient estimator which is able to achieve the CRLB
