Abstract :
This paper proposes a novel integral frequency offset (IFO) estimation method for orthogonal frequency-division multiplexing (OFDM) systems, which examines the phase changes of synchronization signals in frequency domain. It is shown that the new method provides excellent IFO estimation performance with very low computational complexity.
