Abstract
A method of estimating initial channel quality in a receiver when allocated a new channel in order to select an optimal codec mode in a multi-rate service is disclosed. One implementation initially fills the filter state with the first received channel quality measurement. Another embodiment proportionally fills the entire filter state with the calculated channel quality measurements. Yet another embodiment uses the hysteresis and threshold parameters in conjunction with the initial codec mode to calculate an initial fill value for the filter state.
