Performance analysis of variable bit rate multiclass services in the downlink of a dynamic complete partitioning round-robin carrier-hopping multirate multi-carrier DS-CDMA system

Abstract

Analytical formulations of the outage probability in terms of bit error rate specification using Chernoff bound and central limit Gaussian approximation for variable bit rate (VBR) multiclass services in the downlink of a dynamic complete partitioning (DCP) round-robin carrier-hopping multirate Multi-Carrier (MC) DS-CDMA cellular system is presented. The analytical framework is formulated for the general case in which different traffic classes have different spreading gains in each of the subcarriers. The analytical work leads to the determination of the capacity region of a dynamic complete partitioning round-robin carrier-hopping multirate MC-DS-CDMA system for VBR traffic. Numerical results show that the system capacity with DCP can be larger than that with complete sharing (CS) of the subcarriers.
