Performance analysis for mobile relay station with beam steerable antenna

In this paper, beam steerable antenna is deployed in mobile relay station (MRS) on vehicles to increase the link reliability and system flexibility in mobility. With only a single radio frequency (RF) chain, various beam patterns can be formed and selected electronically in a simple and low cost way. We proposed beam switching mechanism to mitigate neighboring interference and improve handover performance. Numerical simulations verified the improved SINR performance (over 15dB) at the cell edge. The handover success rate increases significantly, particularly in high speed mobility.
