In this paper we propose a symmetric transmission scheme for inter-carrier interference in OFDM system.The scheme is bases on two-path phase rotation conjugate cancellation(PRCC) scheme,but uses two way mirror symmetry signals instead of the original conjugate signals with a phase rotation factor at transmitter.At the receiver through reduction treatment,phase rotation can be done automatically.Compared with PRCC,the proposed scheme saves the need for frequency offset estimation and phase factor feedback process and has lower complexity and higher transmission efficiency.

Key words: OFDM;inter-carrier interference;phase rotation conjugate cancellation
