%X In this paper, a distributed resource allocation scheme is developed for OFDMA cellular systems in a downlink transmission. The major impairments considered are co-channel interference and frequency selective fading. The allocation problem includes assignment of sub-carriers, bit loading and power control for multiple users considering their individual QoS as well as the fairness. Exchanging the simple occupation of sub-carriers among cells, the scheme does not result in heave signal load. Simulation results show that the allocation scheme can achieve the tradeoff among different performance objects by adjusting the parameters.
