1. A system comprising:
a controller;
circuitry coupled with the controller and configured to detect a data section of a power line communication (PLC) message, wherein the data section comprises a plurality of logic 0 and logic 1 symbols that are 180 degrees out-of-phase with each other; and
a differential phase detection system coupled with the circuitry and the controller, wherein the differential phase detection system is configured to:
read phases of two adjacent symbols in the data section;
determine whether a phase difference exists between the phases of the two adjacent symbols; and
provide an output to the controller regarding whether the phase difference exists;
wherein the PLC message further comprises a preamble section, and wherein the controller is configured to enable the differential phase detection system to read the phases of the two adjacent symbols in the data section in response to noise in the preamble section exceeding a threshold.
