Abstract
We propose an edge sidelobe suppressor (ESS) for the uplink of OFDMA systems, which mitigates the interference introduced by different frequency offsets between a desired user and other users. The performance of this ESS scheme is evaluated using both the average signal to interference power ratio (SIR) and the average bit error rate (BER). The simulation results confirm that the proposed ESS scheme improves system performance by approximately 10 dB SIR as compared to conventional OFDMA systems, and without increasing the level of transmitter and receiver complexity.
