IEEE communications letters, 1998•ieeexplore.ieee.orgThis 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 the bandwidth efficiency.
