    Abstract: The technology comprises method(s) and apparatus for operating a telecommunications system. In its basic form the method comprises providing plural channelization codes for potential use by an uplink receiver; using unused channelization codes of the plural codes to generate an estimate of an impairment covariance matrix; and using the estimate of the impairment covariance matrix to form a processing parameter. For example, the processing parameter can be one or more weight values which, in turn, are can be used for generating a combined output signal.

    Abstract: Signal quality estimation and demodulation are tailored to the received signal quality. According to one embodiment, a received signal is processed by determined a first set of combining weights based on a first impairment covariance estimate derived assuming a low signal quality environment (300 and 302). A second set of combining weights is determined based on a second impairment covariance estimate derived assuming a high signal quality environment (304 and 306). A metric is determined corresponding to the difference between symbol estimates derived from the second set of combining weights and hard symbol decisions (308). The received signal demodulated based on the second set of combining weights if the metric satisfies a threshold indicating high signal quality and otherwise based on the first set of combining weights (310, 312 and 314).
