Radio Resource Allocation Optimization of the Reverse Link in Multimedia DS-CDMA Systems

摘要

In this paper, we present the theoretical work (model) of the radio resource allocation (RRA) optimization of multimedia DS-CDMA reverse link (uplink) based on QoS constraint models. Our goal is to optimally allocate the users' data rate and power levels to minimize the total transmission power under each accessing user's QoS constraint model, i.e., taking into account user's application BER and data rate requirements. We show that through strict theory deduction, the proposed model provides the optimal joint data rate and power allocation for the reverse link in multimedia DS-CDMA systems.
