Abstract
Aspects of the present disclosure are directed towards a circuit-based apparatus for receiving data communications over power distribution lines that carry power using alternating current (AC). The apparatus has a processing circuit that is configured and arranged to receive an input signal representing the data communications over power distribution lines. For a quadrature encoded signal, the input signal is separated into intermediary signals representing a real portion of and an imaginary portion. The processing circuit can then determine timing information from the real portion of and the imaginary portion. The intermediary signals can then be decimated according to a variable rate of decimation that is responsive to the determined timing information. The decimated intermediary signals are also filtered.
