Abstract
In a data synchronizer a timing error estimator samples a received stream of digitized data symbols at the beginning, end, and a mid-point of a symbol period. These samples are used with a model that assumes that a data stream waveform should transition along a straight line between its values at optimum sampling instances, separated by the symbol period. Differences between a mid-symbol sample estimated using this straight line model and the actual mid-symbol sample are assumed to be due to a timing error. The timing error estimator performs computations on complex inputs and therefore is compatible with a wide variety of modulation types.
