We propose an edge sidelobe suppressor (ESS) for the uplink of orthogonal frequency-division multiple-access (OFDMA) systems, which mitigates the interference introduced by different frequency offsets between a desired user and the other users. The simulation results confirm that the proposed ESS scheme improves system performance by approximately 5-dB signal-to-interference ratio as compared to conventional OFDMA systems, and without increasing the level of transmitter and receiver complexity.
