Patent ID: 8737496

Claim:
A method of computing a signal-to-interference-plus-noise ratio of a signal received on an OFDM carrier over communication channel, said method comprising: jointly detecting symbols in a signal-of-interest received on two or more receive antennas; and computing a signal-to-interference-plus-noise ratio for the signal-of-interest by: computing per-subcarrier signal-to-interference-plus-noise ratios for a plurality of subcarriers allocated to the signal-of-interest by computing interference correlations across said antennas and combining the contributions of each antenna based on the interference correlations to obtain the per-subcarrier signal-to-interference-plus-noise ratios; computing per-subcarrier capacities for the subcarriers allocated to the signal-of-interest based on the per subcarrier signal-to-interference-plus-noise ratios; and computing a total signal-to-interference-plus-noise ratio for the subcarriers based on the per-subcarrier capacities of the subcarriers.
