- In this paper, we consider fast cell site selection (FCS) in packet based OFDM cellular systems. Mobile station (MS) in multi-coverage regions or soft handover region can have opportunities to select a link better than from the current cell. Conventional FCS schemes track the channel fading variation, achieving a selection diversity gain . However, MSs near the cell boundary suffer from other cell interference (OCI) which is highly time-varying and unpredictable. Therefore, it may be desirable for FCS to reduce the OCI effect near the cell boundary. In this paper, we propose an FCS scheme with interference avoidance for a packet based OFDM system and analyze its performance. Finally, the analytic performance of the proposed scheme is verified by computer simulation
