%X Orthogonal Frequency Division Multiplexing (OFDM) systems is very sensitive to frequency errors. An easy pre-coding scheme with rate 1/2 can reduce this sensitivity to frequency offset and compress the inter-carrier interference. A new pre-coding scheme based on the maximum of carrier-to-interference is proposed in this article. It can efficiently find the pre-coding parameter with known frequency offset. The simulation results shown that the new pre-coding scheme can outperform the traditional one.
