摘要：

This study considers the use of frequency-domain correlative coding with correlation polynomial F (D) = 1 - D in OFDM mobile communication systems to compress the intercarrier interference caused by channel frequency errors. A theoretical expression of carrier-to-interference power ratio (CIR) has been derived. It shows that such a simple coding method enhances system CIR by 3.5 dB, without reducing bandwidth efficiency.
