Carrier and Sampling Frequency Offset Estimation and Tracking in OFDM SystemsPublished online: Jun 22, 2009
In This paper presents the proposition of the tracking algorithm of the carrier frequency and sampling frequency offsets. The algorithm uses a phase difference between channel transfer function estimates computed for the same subcarrier of two successive OFDM symbols. Proposed solution was compared, by means of computer simulation, with similar non-data aided algorithm introduced in . Both schemes were tested by transmitting OFDM symbols over the Rayleigh fading channel.
