Abstract

In this paper, a beamforming and cell searching method is proposed for a mobile station (MS) with antenna array to compensate the high attenuation in a millimeter wave (mm-wave) OFDM-based cellular systems. A cell searching and direction-of-arrival (DoA) estimation method is proposed for a multipath environment, even with the existence of the symbol timing offsets (STOs) and carrier frequency offsets (CFOs). It is shown by simulation that the proposed method can successively estimate both cell IDs and DoAs from adjacent base stations (BSs) in a multipath environment and is robust to STO and CFO.
