Abstract :
In this paper, we propose a new multi-rate multiple-access wireless system implemented by variable spreading gain and chip-level random interleaving. Optimization across the physical and network layers in the uplink of such a system is also treated. A multi-criterion reinforcement learning (MCRL)-based adaptive call admission control (CAC) method is proposed which can easily handle multiple average QoS requirements
