Abstract
A method and system for encoding ancillary information at a transmitter in a high-speed communications network, the method comprising: generating an electromagnetic interference (EMI) reduction signal; receiving an ancillary data symbol; generating an EMI reduction signal variation based on the ancillary data symbol; and varying a characteristic of the EMI reduction signal based on the generated EMI reduction signal variation to encode the ancillary data symbol in the varied EMI reduction signal.
