Capacity analysis and call admission techniques for CDMA packet transmission systems

A capacity analysis in order to set an effective threshold for connection admission control (CAC) associated to the reverse link of a multimedia wireless communication system using CDMA has been developed. Packet transmission has been considered for both real time and non-real time services. A centralized demand assignment algorithm has been implemented in order to provide QoS. Performance in a multicell scenario and in time variant wireless channel conditions has been evaluated considering channel-stated scheduling algorithms. Results obtained from the packet level have provided useful information in order to induce capacity bound in a multiservice system. Delay constraints associated to individual traffic classes have been included in our analysis in order to set a more accurate threshold of CAC.
