Abstract
In this paper, estimation of carrier frequency offset (CFO) in orthogonal frequency division multiplexing (OFDM) systems with I/Q imbalance is studied. By exploiting the mirror spectrum induced by I/Q imbalance, we proposed a novel algorithm for blind CFO estimation without training sequences. Simulation results show that the proposed algorithm outperforms the existing one, which is well accepted as a guideline of blind CFO estimation algorithms in OFDM systems.
