Abstract

We propose a subcarrier allocation scheme for Orthogonal Frequency Division Multiple Access (OFDMA) system to provide efficient resource allocation mechanism among multiple users by considering traffic based priority to improve the total system Bit Error Rate (BER) and throughput performances in the multipath fading channel. Since most subcarrier allocation schemes allocate subcarriers in better channel condition for users with different amount of traffic equally, total BER performance is degraded while users with less traffic are assigned with subcarriers in good channel gain. In the proposed scheme, by considering user traffic, better subcarriers are allocated for users with more transmit/receive packets. Our simulation results show that the proposed scheme can provide better system BER and throughput performances compared to the conventional scheme.
