Differential pulse-code modulation (DPCM) methods and systems for encoding cyclic data

摘要

A method includes receiving a first cycle of an original cyclic signal. One or more cyclic parameters of the first cycle of the original cyclic signal are estimated. The original cyclic signal is predicted in counts, based at least partially upon the one or more cyclic parameters and one or more sensor parameters, to produce a predicted cyclic signal that corresponds to the original cyclic signal. The predicted cyclic signal includes biased, dual-state, differential pulse-code modulation (DPCM) data. A second cycle of the original cyclic signal is predicted based upon the predicted cyclic signal.
