OVSF based fair and multiplexed priority calls assignment CDMA Networks

Abstract

Code division multiple access (CDMA) networks uses orthogonal variable spreading factor (OVSF) codes to support different transmission rates for different users which suffers from code blocking limitation. Multiplexing in digitized world is used for data selection. In this paper, calls are multiplexed to share the capacity of the network fairly and with priority using OVSF codes for assignment. A multiplexer is used to provide each call their share of capacity. The different layers shares their capacity with other layer in order to minimize code blocking. Simulation results prove dominance and fairness of our design over other novel schemes.
