Patent ID: 8744020

Claim:
A method of estimating a frequency offset of a received signal comprising a number of subsequently received data symbols, the method comprising the step of determining a first estimate of said frequency offset from a calculated change in phase of the received signal between two received symbols having a first time distance between them, wherein the method further comprises the steps of: determining at least one further estimate of said frequency offset from a calculated change in phase of the received signal between two received symbols having a time distance between them, which is different from said first time distance; determining for each of said first and further estimates a frequency periodicity from the distance between the two received symbols from which the estimate was determined; determining a set of integer values comprising an integer value for each of said first and further estimates so that frequency values calculated for each estimate as a respective frequency periodicity of the frequency periodicity estimates multiplied by a respective integer value of the integer values of the estimates added to the respective estimate are at least approximately equal to each other; and calculating from the determined set of integer values a corrected estimate of said frequency offset.
