Resource allocation for multimedia CDMA wireless system with soft target SIR thresholds
Power control and data rate allocation are two fundamental techniques for improving the spectral efficiency of wireless multimedia communications. In this paper, we study the relation of data rates and target SIR thresholds by minimizing the total transmitted power for given system throughput using DS-CDMA technology. The law that governs the dynamic data rate allocation is analyzed by adjusting target thresholds. Computer simulation results show that user has to sacrifice its target SIR threshold to obtain more resource from the system.
