Abstract :
In this paper we present delay jitter protected-oriented scheduling mechanism for multi-traffic with QoS guaranteed on multi-carrier wireless system. The wireless physical channel quality and the time-delay features requirements of traffics are considered conjointly. When the power is allocated to all sub-carrier according to the water-filling algorithm for maximizing the capacity of the multi-carrier channel, the most emergent packets are scheduled to the sub-channel which is the best quality in multi-carrier frame before AMC adjusting. Analysis and simulation show that the method improves the performance of multi-traffic transmission for multi-carrier systems.
