  Abstract

In this paper, we study cell area extension at handoff of DS-COMA cellular system used adaptive army antenna in the base station to remove multiple access interference effectively in consideration of propagation effect and mobile scatterer distribution. Firstly, SINR for signal that is received from the mobile is derived in consideration of interference gains with antenna element number, envelop correlation with mobile scatterer distribution and cell loading factor. Secondly, additive transmission power of desired mobile to overcome propagation shadowing is calculated in the application of drived SINR to outage probability at handoff. At this time, calculated additive transmission power is used 10 know cell area extension. From the analysis result, the more beam width of multipath signals that enter to adaptive array antenna is increased, the smaller SINR in the base station is. As the result of that, additive transmission power that is required for quality of system is increased and cell coverage is decreased as outage probability is increased at handoff.
