New iterative-scheduling algorithm for OFDMA systems

In this paper, subcarrier allocation problems of wireless Frequency Division Multiple Access systems is studied. The goal of this paper is to introduce new iterative scheduling algorithm for wireless OFDMA systems. These scheduling algorithm maximizes system throughput and guarantees a minimum quality of service for each user. The proposed scheduler is compared to the most used resource allocation algorithms in terms of performance and computational complexity. Based on the simulation results, we note that the proposed scheduling algorithm improves the wireless OFDMA systems performances compared to the classical scheduling methods.
