Abstract :
In this work we perform a queueing analysis of an OFDMA-based and channel-aware resource allocation scheme. We estimate the service characteristics of the queues using extreme value theory and estimate the tail probability of queue size distribution using generating function approach. Based on numerical evaluations it is seen that our estimates are very close to the values obtained by simulations.
