Abstract

In this paper, we propose a reduced complexity resource allocation technique for the downlink of Multiple-Input Single-Output Orthogonal Frequency Division Multiple-Access (MISO-OFDMA) system. The proposed algorithm efficiently allocates frequency resources among users per subcarrier such that a group of users are simultaneously assigned on the same subcarrier with minimum amount of interference through zero forcing beamforming (ZFBF). The proposed algorithm considers quality of service (QoS) in terms of minimum user rate for each user and preserves fairness among users. QoS plays a key role in fulfillment of users demand of high bandwidth data services in modern wireless systems. Simulation results reveals that the proposed algorithm outperforms other reference algorithms in terms of sum rate, minimum user rate, QoS and preserves a very good fairness performance. Complexity of proposed algorithm is measured by execution time needed and compared to reference algorithms. Simulation results show a further reduction in complexity.
