Frequency error correction in a communication system

A receiver in a data communication system, the receiver comprising:

• a frequency error correction unit capable of being operated in at least three frequency error correction phases, the frequency error correction unit being connected to receive an initial frequency error estimate in a first frequency error correction phase, the frequency error correction unit being adapted to compensate the frequency error in a second frequency error correction phase starting from said initial frequency error estimate, and to refine the compensated frequency error in a third frequency error correction phase using a result of said second phase.

A receiver in a data communication system, the receiver comprising:

• a frequency error correction unit adapted to generate a frequency approximation value based on a frequency error estimate, and to start a channel estimation process using said generated frequency approximation value, said frequency error correction unit being further adapted to refine said generated frequency approximation value, and to compensate a frequency error using the refined frequency approximation value.

An integrated circuit chip for use in a data communication receiver, the integrated circuit chip comprising:

• a frequency error correction circuit capable of being operated in at least three frequency error correction phases, the frequency error correction circuit being connected to receive an initial frequency error estimate in a first frequency error correction phase, the frequency error correction circuit being adapted to compensate the frequency error in a second frequency error correction phase starting from said initial frequency error estimate, and refine the compensated frequency error in a third frequency error correction phase using a result of said second phase.
