Interest in broadband wireless access has been growing due to increased user mobility and the need for data access at all times. This paper aims to study the performance of low complexity adaptive resource allocation in downlink of OFDMA for WiMAX systems with variable rate requirements. Objective of the proposed algorithm is to maximize total throughput while maintaining rate proportionality among the users. The proposed algorithm prioritizes the user with the high sensitivity to the subcarrier allocation. Simulation results shows that proposed method performs better than previous method in terms of significantly decreasing the computational complexity and achieve higher capacities, while being applicable to a more general class of systems.
