Abstract
An apparatus and method for recovering packet data with unknown delays and error transients is disclosed that includes a received waveform containing a desired information signal relative to a fixed reference, for eliminating an undesired error in the received waveform where the error is localized in time relative to the received waveform to a transient interval, and recovering the desired information signal. Included also is a sampler, responsive to the received waveform, providing a series of time samples representative of the received waveform. A buffer, responsive to the time samples, for providing a plurality of representations of the received waveform at different instants of time, where the length of time is an appreciable duration of a transient interval. A reference slicker, responsive to the plurality of representations, for providing an estimate of a fixed reference. A signal recovery circuit, for comparing the plurality of representations with the estimate of the fixed reference, for purposes of recovering the desired information.
