Title

A Blind Maximum Likelihood Carrier Frequency Offset Correction Approach For Ofdm Systems Over Multipath Fading Channels

Abstract

In orthogonal frequency division multiplexing (OFDM) systems, carrier frequency offset (CFO) destroys the orthogonality between subcarriers and hence introduces intercarrier interference. In this paper, a maximum likelihood CFO correction (ML-CFOC) approach is proposed to compensate for the deleterious effects of CFO. The ML-CFOC method exploits the independence between the desired signals and is based on a novel simplified independent component analysis algorithm. The proposed ML-CFOC approach is successfully implemented for OFDM systems over multipath fading channels without requiring training sequences. Computer simulations are given to illustrate the optimal performance of the ML-CFOC. © Birkhauser Boston 2007.
