摘要

DS-CDMA networks are fast evolving from voice only networks to multi-service networks. A key requirement for next generation networks is the ability to support a heterogeneous mix of services with varying traffic characteristics. Many papers assumed fixed capacities in their analysis which is applicable to FDMA and TDMA. Only recently have papers in the literature begun to analyze the effect of soft capacity and soft handoff on network performance. To the authoru27s best knowledge, there is none that analyzes the impact of soft handoff on multi-service DS-CDMA cellular networks. This thesis delineates the impact of soft handoff and user mobility on QoS parameters of multi-service DS-CDMA networks. The main contribution of this thesis is analytical model that includes soft handoff while supporting voice and video with user mobility taken into account. System performance parameters such as call blocking probability and call dropping probability are analytically determined using Markov Chain Analysis.
