Abstract: The invention concerns receive circuitry for demodulating an input signal received from a transmission channel, the receive circuitry having a decision feedback equalizer (228) including an inter-carrier interference estimation block (324) arranged to provide an estimation (RICI(n)) of inter-carrier interference (ICI) noise based on at least a channel estimation (?STAT(n?1)) determined for a previous symbol, a channel estimation (HSTAT(n+1)) determined for the next symbol, and on a previous estimation (?i?1(n)) of the symbol data for the current symbol, the previous estimation being provided by a feedback path comprising a demapping block (314); and correction circuitry (310, 312, 314, 316) arranged to determine the estimation of the original data signal based on the estimation of ICI noise subtracted from the input signal.
