| Abstract: | This paper studies the influence of the soft handoff parameters such as active set add threshold and delete threshold on the system performance in the multiservice CDMA cellular mobile communication systems. The relationship between the call outage probability and soft handoff rate versus the active set add threshold and delete threshold is simulated, and some conclusions are drawn. Then reasonable active set add threshold and delete threshold are got, which can give a reference for designing a real system. |
