摘要： A radio signal transmitted from a transmitter to a receiver of a mobile communications system, such as the GSM system, often suffers from a phenomenon known as frequency offset by which the frequency of the radio signal is changed from a first frequency to a second frequency. A method is therefore provided for automatically correcting the frequency at the receiver to restore the received radio signal to approximately the first frequency using a multistage frequency correction algorithm. The radio signal comprises a training sequence that is known to the receiver and data symbols that are not known to the receiver. In the first stage of the frequency correction, the frequency offset is coarsely estimated based on the training sequence only, and the data symbols are frequency corrected by back-rotating the received data symbols and the training sequence by the frequency offset estimate. The frequency corrected data symbols and training sequence are then input into the second stage of the frequency correction where they are used to determine a second estimate of the frequency offset that should be more accurate because the second estimate of the frequency offset is based on a larger number of symbols including symbols in the previously frequency corrected training sequence and data symbols. Using this second frequency offset estimate, the data symbols in the received radio signal are frequency corrected by back-rotating the received data symbols by the second frequency offset estimate and are output for detection.
