In order to reduce the co-frequency interference for multi-cell OFDMA system, a multi-cell dynamic subcarrier allocation scheme was proposed for downlink orthogonal frequency division multiple access (OFDMA) cellular system. The proposed scheme reduces the powers of co-frequency users, which matches access control to maximize the distances between co-frequency subcarriers users. As a result, the proposed scheme satisfies their quality of service (QoS) requirements, and improves wireless resources utilization rate. Simulation results show that the proposed scheme is superior to other existing schemes. It also shows that the proposed scheme satisfies users' QoS and increases throughput of the system.
