Abstract

This paper introduces a reuse partitioning-based dynamic channel allocation algorithm that guarantees quality of service (QoS) by considering fairness among mobile stations in an OFDMA/FDD system. To improve the SINR values for users around the cell edge and increase the overall system throughput compared with the conventional OFDMA/FDD system of frequency reuse factor (FRF) 1, an effective transmit power allocation algorithm is also combined with the proposed dynamic channel allocation to adjust the transmit power per user according to the average received SINR value. Simulation results show that the proposed DCA algorithm increases the sector throughput by about 25% when compared with the conventional case that do not apply the proposed DCA algorithm. When the proposed transmit power allocation algorithm is combined with the proposed DCA algorithm, a further increase in the sector throughput of about 6% is achieved than when using just the proposed DCA algorithm.
