Abstract

Frequency offset is a common problem in orthogonal frequency-division multiplexing (OFDM) systems. This causes the orthogonality between subcarriers to be lost and results in intercarrier interference (ICI). A promising ICI self-cancellation scheme has been proposed (see Zhao, Y. and Haggman, S.-G., IEEE Trans. Commun., vol.49, no.7, p.1185-91, 2001) to reduce the effect of frequency offset error. The performance of the scheme, however, has not been fully analyzed. We analyze a theoretical performance of OFDM systems with ICI self-cancellation, where the ICI is treated as Gaussian noise. A tight bit error rate (BER) upper bound expression is derived and verified by simulation results.
