Abstract
Orthogonal frequency division multiplexing (OFDM) systems are highly sensitive to ICI caused by carrier frequency errors, so reliable time and frequency synchronization is crucial for the system. In this paper, a new method combined DA (PN estimation) and NDA (ML estimation) method to do frequency synchronization in frequency domain is proposed with large estimation range. Simulation and performance analysis show that our overall frequency estimator has high accuracy.
