Li, Duo (2003) Simulation of QoS based call admission schemes for DS-CDMA. Masters thesis, Concordia University.
Code division multiple-access (CDMA) has been receiving considerable attention as the core multiple-access technology in the development of upcoming ubiquitous personal communication service (PCS) system with flexible quality of service (QoS) requirements at any time and anywhere. Moreover, future wireless networks are expected to integrate different types of multimedia traffic, such as voice, data, and compressed images and video. This work aims to investigate the resource allocation problem for wireless direct sequence spread-spectrum CDMA cellular networks supporting heterogeneous multimedia applications where individual users have different QoS requirements. We propose optimal rate and power distribution approaches for source allocation to individual users, subject to a constraint on the total available bandwidth, to maximize the per-cell capacity and maintain the quality of service (QoS) for different multimedia services. Connection oriented admission control schemes based on the required QoS are proposed in this thesis. Several policies are introduced for use in CDMA network. Simulation results show that the proposed Radio Resource Management scheme can achieve both effective QoS guarantee and efficient resource utilization.
