Frequency Offset Estimation for Unknown QAM Constellations
Stefania Colonnese, Stefano Rinauro, Gaetano Scarano · IEEE Transactions on Communications · 2012
We introduce a novel, both gain and signal-to-noise ratio independent, constellation unaware, blind frequency offset estimation procedure for QAM signals. Asymptotic performance analysis and numerical simulations show that the herein presented method outperforms a selected state of the art blind constellation unaware estimator, especially for cross constellations.
