In this paper, a modified symmetric symbol repetition (MSSR) scheme is presented for reducing the effect of intercarrier interference (ICI) due to the frequency offset. The proposed scheme improves the carrier-to-interference ratio (CIR) by reducing the ICI in the presence of frequency offset. The proposed MSSR exploits the frequency diversity over the frequency-fading channel and thereby achieves better BER performance compared with that of conventional intercarrier interference reduction techniques such as adjacent symbol repetition (ASR) and symmetric symbol repetition (SSR).
