A Novel Algorithm for Multiuser Resource Allocation of OFDM

Abstract

Orthogonal Frequency Division Multiplexing is considered as the key technology of the fourth generation of mobile communication technology. In this paper, an idea is proposed which solves the issue of multiuser resource allocation for OFDM based on swarm intelligence theory, and terminal bandwidth limitation is set as constraints addition as well. Theoretically, swarm intelligence algorithm could allocate resources more efficient and simulation results show that the proposed method is able to achieve better performance and higher system data rate than other similar algorithms under the same condition.
