Abstract: In this paper, we propose a zero correlation zone (ZCZ) sequences-based carrier frequency offset estimation algorithm for interleaved OFDMA uplink. By introducing the effective carrier frequency offset (CFO) and designing an appropriate training sequence for each user, we propose a training sequence-based CFO estimation algorithm thus avoiding the computationally complex subspace-based method proposed by Cao & Tureli (2002). Zero correlation zone sequence set is used as training sequence to mitigate multipath inference and multiuser inference. Simulation results show that the proposed algorithm is effective in multi-path fading channel
