A joint AOA, AOD and delays estimation of multipath signals based on beamforming techniques

Angle of Departure (AOD) and Delay of Arrival (DOA) information is added to beamforming techniques to provide improved and more robust estimates of Angle of Arrival (AOA) and localization. A joint AOA, AOD and DOA algorithm based on the Capon Beamformer is proposed to reduce complexity and computation time compared to subspace-based methods. The proposed approach works even if the number of multipaths exceeds the number of antenna elements. Simulation results are provided to assess the improvements in channel estimation for a multiple antenna array.
