Abstract

A method of estimating a signal to interference ration (SIR) comprising: estimating the signal power of a signal received at a first time estimating the interference power of a signal received at a second time preceding the first time; and combining the signal power estimate at the first time and the interference power estimate at the second time to produce an estimate of the signal to interference ratio at the first time.
