  Abstract

This paper proposes a frequency offset estimation scheme with low-complexity for orthogonal frequency division multiplexing (OFDM)-based cognitive radio (CR) systems. The proposed scheme is applicable to any type of training symbol and has a lower complexity than the scheme in [9] by using the partial periodogram. Simulation results show that the estimation performance of the proposed scheme is almost the same as that of the scheme in [9].
