Abstract :
In mobile reception of OFDM, the bit error rate characteristic is deteriorated, because the inter-carrier interference(ICI) is generated by the Doppler-spread of radio channel. The influence of ICI can be reduced by ICI canceller based on zero-forcing equalization. In this paper, Zero-forcing ICI canceller using the linear interpolation is studied in order to reduce the complexity of the circuits. As the result of simulation, the proposed ICI canceller can achieve performance equivalent to the conventional scheme with less complexity.
