  • In this paper, an optimal adaptive multiuser subcarrier allocation with partial-channel response is proposed. This algorithm reduces computational complexity without apparent performance attenuation based on multiusers feedback information and dynamic subcarrier allocation method by considering partial-channel response caused by delayed feedback information or estimate error. Simulation results show that the proposed method decreases the impact of partial-channel response and computational complexity obviously with gaining an approximative performance compared with traditional subcarrier allocation method at the same time.
