On Joint Angle and Delay Estimation in the presence of local scattering

We present a novel 2D-MUSIC algorithm that can jointly estimate the angles and times of arrival of multiple signals in the presence of local scattering. We focus on a scenario where the received signal is a sum of “clusters”, and each cluster is composed of multi-incident rays that show similar angles and times of arrival. The setting is composed of a Single-Input-Multiple-Output (SIMO) link where the transmitted signal is an OFDM symbol. Simulation results show the potential of the proposed algorithm compared to the traditional 2D-MUSIC algorithm that doesn't take into account local scattering.
