A method of estimating interference and noise of a communications channel includes receiving a data sequence transmitted over the communications channel at a receiver, and computing a sequence of channel estimates based on the received data sequence. The method also includes 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. |
