Abstract
The invention concerns receive circuitry for demodulating an input signal received from a transmission channel, the receive circuitry having a decision feedback equalizer including an inter-carrier interference estimation block arranged to provide an estimation of inter-carrier interference (ICI) noise based on at least a channel estimation determined for a previous symbol, a channel estimation determined for the next symbol, and on a previous estimation of the symbol data for the current symbol, the previous estimation being provided by a feedback path comprising a demapping block; and correction circuitry arranged to determine the estimation of the original data signal based on the estimation of ICI noise subtracted from the input signal.
