<p>Methods and systems are provided which calculate a carrier to interference ratio of a channel using an approach which accounts for variations in the channel response characteristics over the estimation evaluation time period. The time variations may be taken into account by various alternative approaches including breaking the sample period into a series of sub-sample estimation windows and applying a different constant channel response estimate to each sub-sample estimation window or by applying a time varying model to the channel when generating the channel response estimate (such as a least squares error fit to a first order or higher order equation). Accordingly, the systems and methods of the present invention may provide for improved estimates of the carrier to interference ratio, particularly for channels subject to multi-path fading effects such as those which may result from movement of a mobile terminal during measurements of the channel.</p> |
