In wireless communication systems, frequency offset exists at the received signal due to the transmitter-receiver oscillator mismatch and Doppler Effect in mobile environments. Those offsets rotate the received signal’s phase and degrade the receiver performance. Hence, estimation and compensation of the frequency offset is crucial at the receiver. This paper proposes a new frequency offset estimation technique based on partial correlation. The proposed method requires less computational complexity than the conventional method while the proposed one can estimate a wide range of frequency offset without estimation accuracy loss. Therefore, the proposed technique is adequate for the communication environments that have a large frequency offset. To verify the performance, computer simulation is conducted and comparison with the conventional method is presented as well.
