System, method and apparatus for communication that is insensitive to a sampling clock error

Abstract

A system, method and apparatus for digital communication that is insensitive to a sampling clock error. In one embodiment, a digital communication system that is insensitive to a sampling clock error is provided. The digital communication system includes a transmitting communication unit and a receiving communication unit. The transmitting communication unit is configured to generate a digital data communication signal and includes a modulator configured to modulate digital data such that the modulated digital data communication signal is invariant to a stretched frequency scale resulting from a lack of synchronization with a receiving communication unit. The receiving communication unit is configured to receive the digital data communication signal and includes a demodulator configured to demodulate the digital data.
