Patent ID: 7995688

Claim:
A method comprising: a) receiving at a receiver a signal, the signal comprising a plurality of subcarriers; b) processing the signal by performing pilot-aided channel estimation for determining a first estimate of channel gain at each subcarrier; c) determining a decision signal in dependence upon the first estimate of channel gain at each subcarrier; d) determining an estimate of channel gain at each subcarrier corresponding to a diagonal vector of a channel frequency response matrix and an estimate of inter carrier interference gains at each subcarrier corresponding to off-diagonal vectors of the channel frequency response matrix in dependence upon the received signal and the decision signal; e) canceling inter carrier interference in dependence upon the estimate of channel gain at each subcarrier and the estimate of inter carrier interference gains at each subcarrier and updating the decision signal; f) repeating d) and e) until a stopping criterion is satisfied; and g) providing the decision signal.
