Abstract
This letter proposes a subchannel renumbering (SCR) scheme to improve frequency resource utilization in IEEE 802.16 OFDMA systems. SCR rearranges the logical subchannel numbers to derive a group of contiguous subchannels with a high burst profile such that BS can allocate these subchannels to MSs to enhance system throughput. Simulation results validate that SCR can achieve higher subchannel utilization and system throughput, compared with the existing approaches.
