摘要：Method and apparatus that compensates for overestimation of channel SINR
due to overfitting of an adaptive equalizer to the pilot portion of a received frame. TheSINR of a wireless channel is estimated by adapting an adaptive equalizer using the pilotportion of the frame, applying the adaptive equalizer to a non-pilot portion of the frame,determining a parameter using the adaptive equalizer output, and estimating the SINR ofthe wireless channel using the parameter. The parameter can include, for example, themean square error (MSE) or the bias of the equalizer output. The accuracy of the SINRestimate according to this aspect of the present invention is thereby improved (ascompared to a SINR estimate based on parameters calculated during the pilot interval)because the adaptive equalizer is not overfit to the control or data portions of the frame.
