Abstract
A chirp waveform is employed in establishing timing synchronization between nodes of a data communication network. In one embodiment, the chirp waveform is combined with a waveform modulated with data to form a synchronization waveform. The receiver of the synchronization waveform determines an alignment of the chirp waveform to a template chirp waveform to synchronize timing between nodes.
