Abstract

This paper addresses the problem of carrier frequency offset estimation in OFDM systems. Perfect time synchronization and burst transmission are assumed. A preamble consisting of a series of identical blocks is available for the frequency offset estimation. The proposed estimator is based on the correlation of two blocks, which is a commonly used approach. In contrast to existing papers, the author shows here how to adjust the correlation parameters in order to exploit the periodic structure of the preamble and to obtain best estimation results. The degree of accuracy of the estimates obtained using the proposed method is compared with the Cramér-Rao lower bound.
