1. An OFDM receiver comprising of a baseband portion, where said OFDM receiver receives a precoded OFDM transmit signal comprising of precoded pilot tones and precoded data tones, further where said precoded OFDM transmit signal relies on at least one of time index of a subcarrier of said precoded OFDM transmit signal;

  • frequency index of said subcarrier; and

    time and frequency indices of said subcarrier and is transmitted using a plurality of antennas, said baseband portion further comprising of at least one means adapted for;

    estimating channel state information using said precoded pilot tones;

    estimating interference covariance estimation using said precoded pilot tones;

    demodulating said precoded data tones; and

    computing filter weights using said channel state information and said interference covariance estimation.
