Abstract

Orthogonal frequency division multiplexing (OFDM)communication systems, convert a frequency selective fading channel into several nearly flat fading channels. A well known problem of orthogonal frequency division multiplexing (OFDM), however, is its sensitivity to frequency offset between the transmitted and received signals. This carrier frequency offset causes loss of orthogonality between sub-carriers which results in inter-carrier interference (ICI). This paper studies an efficient ICI cancellation method termed ICI self-cancellation scheme for Binary Phase Shift Keying (BPSK). The results show that by using the self ICI cancellation scheme proposed here, the ICI can be reduced significantly. Therefore this OFDM system suffers much less from performance degradation caused by frequency errors than the normal OFDM systems.
