Abstract  This comment points out some inaccurate formulae, and shows some irrelevant comparison of different estimators. Moreover, the correct formulae are provided and the modification to the fractional frequency offset (FFO) estimator is indicated. On the other hand, Our analysis have shown that the integer frequency offset (IFO) estimator of Ai is of serious theoretic problem.
