Abstract

In millimeter wave (mmWave) systems, analog beam steering (i.e., direction of arrival (DOA) estimation) is an essential operation for subsequent channel estimations. In this paper, we propose a framework of incorporating a monopulse ratio (MR) concept, originally developed for radar systems, into an orthogonal frequency division multiplexing (OFDM) mmWave systems with cyclic prefix (CP) for DOA estimation. It is shown that CP can be used for DOA estimation in general OFDM mmWave systems by employing the MR concept. Based on performance analysis and simulation results, the proposed method can be considered as a practical and robust DOA estimation method for single RF chain analog beamforming systems.
