Device and method for frequency offset estimation

A method for estimating a frequency offset of a signal, comprising:

• receiving the signal, by a mobile terminal, comprising a plurality of data parts, wherein the plurality of data parts comprise payload data and known symbols;
• decoding the received signal;
• reconstructing the plurality of data parts by remodulating and filtering the plurality of data parts and outputting a plurality of reconstructed data parts;
• generating a product of the plurality of the data parts with a conjugation of the plurality of reconstructed data parts;
• calculating a plurality of phases from the product generated for each of the plurality of the data parts;
• and
• estimating the frequency offset from the plurality of phases.

A non-transitory, computer program product comprising program codes, which, when run on a computer, causes the computer to perform a method, the method comprising:

• receiving a signal, by a mobile terminal, comprising a plurality of data parts, wherein the plurality of data parts comprise payload data and known symbols;
• decoding the received signal;
• reconstructing the plurality of data parts by remodulating and filtering the plurality of data parts and outputting a plurality of reconstructed data parts;
• generating a product of the plurality of the data parts with a conjugation of the plurality of reconstructed data parts;
• calculating a plurality of phases from the product generated for each of the plurality of the data parts;
• and
• estimating the frequency offset from the plurality of phases.
