Abstract:
1. A method of operating a telecommunications system comprising: providing plural channelization codes for potential use by an uplink receiver; using unused codes of the plural channelization codes to generate an estimate of an impairment covariance matrix associated with an anchor uplink receiver by: obtaining delay values from plural uplink receivers; forming a superset comprising the delay values; associating fingers with each of the delay values in the superset; determining the impairment covariance matrix using unused codes over all delay values in the superset; obtaining from the impairment covariance matrix a first subset of the impairment covariance matrix, the first subset pertaining to the delay values for an anchor uplink receiver; using the first subset of the impairment covariance matrix to form a processing parameter for the anchor uplink receiver.
