PERFORMANCE ANALYSIS OF HANDOFF SCHEME IN MOBILE RADIO SYSTEMS WITH SMART ANTENNAS

摘要

Smart antenna is suggested to be used in future mobile radio communication systems to provide service with high capacity and quality. In this paper, we propose an analytical model for a novel mobile radio communication system with smart antennas. In the proposed system, several beams with same channel (frequency, time slot or code) are formed in a cell. Higher priority is assigned to handoff requests over originating calls. The system is modeled and analyzed by a two-dimensional Markov chain. Blocking probability of originating calls and forced termination probability of hand-off requests are obtained from our formulae. As we expect, the system capacity and performance are highly improved by employing smart antennas.
