Summary: Received signal Direction of Arrival (DOA) estimation is a significant problem with wide-ranging applications. Current approaches struggle to separate closely located transmitters without using a large number of antennas, resulting in higher costs. In this paper, we propose a deep learning framework that can estimate DOA under Line-of-Sight scenarios, distinguishing more closely located sources than the number of receiver's antennas. Our approach reduces hardware complexity compared to state-of-the-art solutions and performs well in demanding scenarios with low SNR and limited snapshots.
