Abstract
In a disclosed embodiment, a power line communication (PLC) transmitter includes a forward error correction (FEC) encoder that receives payload data and adds parity information to the data to create an encoded output, a fragmenter that receives the encoded output from the FEC encoder and segments the encoded output into a plurality of fragments, a fragment repetition encoder that receives the plurality of fragments from the fragmenter and copies each of the fragments a selected number of times, and an interleaver that receives the copies of the plurality of fragments from the fragment repetition encoder and interleaves the copies of the plurality of fragments for transmission on a power line.
Claims1
An electronic device comprising:
- a forward error correction (FEC) encoder configured to receive payload data and adds parity information to the data to create an encoded output;
- a fragmenter that receives the encoded output from the FEC encoder and segments the encoded output into a plurality of fragments;
- a fragment repetition encoder that receives the plurality of fragments from the fragmenter and copies each of the fragments a selected number of times;
- and
- an interleaver that receives the copies of the plurality of fragments from the fragment repetition encoder and interleaves the copies of the plurality of fragments for transmission on a power line.
