Abstract :
A novel intercarrier interference (ICI) cancellation scheme for orthogonal frequency-division multiplexing (OFDM) wireless communication systems is proposed. By equivalently representing the OFDM system with a synchronous code-division multiple access (SCDMA) model, the schemes for the multiple access interference (MAI) cancellation in the SCDMA model can be directly applied to the ICI cancellation in the OFDM system. In addition, the signal detection delay can be further improved by making use of the correlation between the neighboring subcarriers. Simulation results to demonstrate the effectiveness of the proposed ICI cancellation scheme are presented.
