title = "Blind frequency synchronization for OFDM system with I/Q imbalance",
abstract = "In this paper, we propose a new blind frequency synchronization scheme for an OFDM system with I/Q imbalance. A blind estimation of joint CFO and I/Q imbalance parameters is first developed by exploiting the multi-antenna redundancy at the receiver. The estimation computational complexity is reduced by expressing the cost function as a superposition of very few harmonically related cosine waves. The compensation for CFO and I/Q imbalance can be further carried out, which would result in an equivalent received signal model without CFO and I/Q imbalance distortion. Then the conventional channel estimation and data detection can be performed. The Cramer-Rao bound (CRB) of the CFO estimation is derived. We also provide numerical simulations to demonstrate the superiority of the proposed method over the existing competitors.",
