title = "A chirp-based frequency synchronization approach for flat fading channels",
abstract = "In different new and emerging technologies, where high frequency offsets (FOs) are expected due to the low-cost nature of the local oscillators, and low sampling rates are chosen for the sake of power efficiency, accurate FO estimation becomes a challenging task. This work proposes a frequency synchronization approach based on a dual-chirp training sequence. Its performance is evaluated by means of simulations and validated with the derived Cramer-Rao lower bound. It is shown that the proposed method achieves near-optimum performance with lower complexity than the state-of-the-art approach.",
