Abstract
Systems and methods for digital communication using an inexpensive reference crystal are described herein. Some illustrative embodiments include a method that includes setting a center frequency of a local oscillator used by a radio frequency (RF) transceiver, sequentially applying each of a plurality of predetermined offsets to the center frequency of the local oscillator, determining a plurality of metrics indicative of the quality of a received signal (each of the plurality of metrics corresponding to a different predetermined offset of the plurality of predetermined offsets), and selecting a predetermined offset of the plurality of predetermined offsets that results in a metric indicating a received signal that is higher in quality than the received signal that results when applying each of the remaining predetermined offsets of the plurality of offsets.
