A Novel Carrier Frequency Offset Estimation and Tracking Scheme for OFDM
一种新的OFDM系统载波频率偏移估计和跟踪方案

In this paper, a carrier frequency offset estimation and tracking scheme for OFDM is presented. Pilot-Symbol-Aided (PSA) estimation is used to estimate carrier frequency offset in OFDM system, and the carrier frequency tracking applies the cyclic prefix. The simulation results prove the PSA estimation of frequency offset is precise, and the carrier frequency tracking is available.
