1. A method of record processing comprising:
- receiving an oversampled record of symbols capturing a data burst;
obtaining, with one or more metrics, a reduced number of samples representative of the symbols from the oversampled record of symbols;
estimating a residual carrier phase and frequency utilizing at least a subset of the reduced number of samples;
removing at least part of the estimated residual carrier phase and frequency from the reduced number of samples to produce a first corrected set of symbols; and
resolving a calculated phase ambiguity for the first corrected set of samples to produce a second corrected set of symbols.

Abstract
Architecture for processing a record of burst information in a transmission link. A waveform sampler samples a received waveform containing a record of symbols imposed on a carrier signal. Symbol phase of the record symbols is determined utilizing one or more metrics. Any residual carrier error is corrected, and the carrier signal is removed. The phase and time-of-arrival of the burst information associated with a maximum positive correlation value are then determined.
