Abstract
In various embodiments, a power-line communication apparatus provides data over a power-line communication network by transmitting data symbols to endpoint circuits over a power line. The power-line communication apparatus includes a signal-processing circuit configured to combine a plurality of different data streams, each of the plurality of different data streams respectively formatted according to different communication schemes, to form a signal that represents a combination of the different data streams and corresponding communication schemes. Further, the power-line communication apparatus includes a pulse-modulation circuit configured to convert the signals, as combined, as a pulse-width modulated or a pulse-density modulated signal, the pulse-modulation circuit configured to switch at a frequency higher than frequencies of the different communication schemes. An output circuit can be configured to filter the switching frequency and to couple the data symbols to an injector transformer for presentation to the endpoint circuits.
