The intercarrier interference (ICI) will occur when the orthogonality between subcarriers is destroyed in orthogonal frequency division multiplexing (OFDM) communication system. ICI caused by frequency offsets is analyzed, and an algorithm based on symmetric symbols is proposed after researching on the typical ICI self-cancellation scheme. The simulation results show that, compared with the self-cancellation scheme, this algorithm not only reduces the intercarrier interference (ICI) coefficient, but also greatly improves the carrier-to-interference power ratio (CIR) and the performance of the system.
