Abstract
A method for estimating a frequency error in a communication system, in particular in a mobile communication system involving successively sampling sample sets from a signal to be received at given points corresponding to symbol sequence points of the receiver, and frequency error estimates corresponding to each point are determined based on the sample sets at the given points and variance of the frequency error estimates of every given point is calculated. The frequency error estimate of the signal to be received is selected based on the frequency error estimates of the given point whose variance is least.
