Abstract
propose a mobile relay structure for vehicles with multiple antennas, which can increase performances of mobile communication systems and broadcasting systems significantly. Since cell searching and DoA estimation are required for the terminal in hard handover cellular system, joint techniques for cell searching and DoA estimation are proposed to apply beamforming technique for the mobile relay with multiple antennas located at the cell boundary. The proposed cell searching and DoA estimation techniques are evaluated by computer simulation under the environment similar to WiBro system.
