Abstract

In this paper, a mobile relay station (MRS) for vehicles with a beamforming antenna is considered to increase the reliability of a transmission link, especially for the MRS at cell boundary. Cell searching and direction-of-arrival (DoA) estimation method for an MRS with a uniform linear array (ULA) is proposed for a multipath environment in OFDM-based cellular systems. Performances of the proposed method are evaluated by computer simulation with the standard profile of IEEE802.16e.
