Abstract
Embodiments of the invention provide a device and a frame structure for powerline communications. The header may comprise two parts that are separately encoded. A common header segment is encoded alone, and an embedded header segment is encoded with payload data

1-22. (canceled)
A device for encoding a physical (PHY) frame, said device comprising:
- a header generation circuit for generating a header with a set of common header bits and a set of embedded header bits;
- a header encoder circuit comprising:
- a forward error correction encoder for providing the header with a common header segment using the common header bits;
- and
- a payload encoder circuit comprising a forward error correction encoder for providing a data segment that includes an embedded header segment generated from the set of embedded header bits.

A physical (PHY) frame for use in powerline communications (PLC), said frame, comprising:
- a preamble;
- a data portion containing:
- an embedded header, encoded with a robust modulation and coding method for providing a PLC device instructions with instructions regarding identification information (ID);
- a payload portion;
- a common header, encoded with a robust modulation and coding method for providing the PLC device instructions on the length of the payload portion.
