Many analytical approaches have been proposed for handoff analysis because handoff is an important technology in mobile communication systems. In CDMA systems with soft handoff, mobile stations (MS's) within a soft handoff region (SR) use multiple radio channels and receive their signals from multiple base stations (BS's) simultaneously. Therefore, SR size, MS's speed and arrival rate of calls have very great influence on handoff process. In this paper, we study the performance of soft handoff in CDMA systems where is based on the square model. The effects of SR size, MS's speed and call arrival rate on call blocking probability are investigated. The results are compared with hard handoff.
