【Abstract】 In order to efficiently utilize limited transmit power and frequency resource in the single-user orthogonal frequency division multiplexing system,intense research interest has focused on new algorithms on resource allocation.This paper introduces a scheme of resource allocation based on greedy algorithm,which displays perfect performance.But it could not satisfy the application requirements due to its complexity.Therefore proposes another algorithm for resource allocation with low complexity and greater value for application.The computer simulation results indicate that this algorithm could reduce the complexity of calculations and utilize limited system resource efficiently,thus enhances the spectrum utilization and system capacity.更多还原
