Abstract
A power line communication (PLC) device is provided which communicates with another PLC device via a PLC signal transmitted over a wire in a broadband. The PLC signal comprises at least one frame. The at least one frame comprises a preamble, a frame control header and a payload. The preamble comprises at least one synchronization symbols used for a PLC engine to synchronize; at least one preamble code symbols used for specifying at least one of a sub-channel and a modulation mechanism; and at least one channel estimation symbols used for the PLC engine to do channel estimation.
Claims18
A power line communication (PLC) device for communicating with another PLC device via a PLC signal transmitted over a wire in a broadband, comprising:
- a PLC engine configured to encode or decode the PLC signal,
- wherein,
- the PLC signal comprises at least one frame,
- the at least one frame comprises a preamble, a frame control header and a payload, and
- the preamble comprises:
- a plurality of synchronization symbols used for the PLC engine to synchronize;
- a plurality of preamble code symbols used for specifying at least one of a plurality of modulation mechanisms and a plurality of sub-channels in the broadband;
- and
- a plurality of channel estimation symbols used for the PLC engine to do channel estimation.
A power line communication (PLC) method applied to a PLC device having a PLC engine to communicate with another PLC device having another PLC engine via a PLC signal transmitted over a wire in a broadband, comprising:
