1. A method of estimating interference and noise of a communications channel, comprising:

  • receiving a data sequence transmitted over the communications channel at a receiver;

    computing a sequence of channel estimates based on the received data sequence;

    computing a difference sequence based on the sequence of channel estimates and the sequence of channel estimates subjected to a displacement in time or frequency; and

    determining a covariance measure of the difference sequence as an estimate of the interference and noise of the communications channel.
