Carrier and Sampling Frequency Offset Estimation and Correction in Multicarrier Systems
In this paper, we present a pilot-aided sampling and carrier frequency offset estimator in orthogonal frequency-division multiplexing (OFDM) systems. The proposed algorithm enables joint carrier and sampling frequency-offset estimation from a pilot whose duration is only two symbol periods. Furthermore, we propose time-domain signal processing algorithms for carrier and sampling frequency offset correction, which do not require time-consuming signal interpolation, and with which fixed free-running oscillators can be used. The performance of the proposed algorithms is studied through simulations, and compared to the performance of the other algorithms described in the literature.
