A dynamic programming algorithm for downlink throughput optimisation in wideband CDMA systems
Mustafa K. Gurcan · 2002
This paper develops an approach for the maximisation of throughput in the downlink of third generation mobile systems, based on wideband CDMA. A mathematical model is outlined for a multi-service multiplexed environment, with constraints placed on the system, based on the class of service. The optimisation problem is stated in terms of the model parameters and adapted for use with a dynamic programming algorithm. Results are presented, showing a significant improvement in throughput when high loads are placed on the system, compared with a fixed bit-rate allocation.
