Application: Data encoder for power line communications (Patent ID: US20230421201A1)
The patent filed by Texas Instruments Inc. describes a power line communication (PLC) transmitter that utilizes a forward error correction (FEC) encoder to add parity information to payload data, a fragmenter to segment the encoded output into fragments, a fragment repetition encoder to copy and repeat the fragments, and an interleaver to interleave the fragments for transmission on a power line. The method involves generating a header with different modulation and coding schemes for different portions of the header, including a modulation and coding scheme indication field, and transmitting the frame with the header and payload using FEC encoding techniques, Reed-Solomon encoding, repetition encoding, and channel interleaving.
The patent further details the generation of the payload by adding error correction codes, dividing into fragments, repeating fragments, interleaving, and concatenating to produce an encoded payload block. The method also includes transmitting a preamble before the header, utilizing orthogonal frequency division multiplexing (OFDM) symbols in the frame, incorporating a medium access control (MAC) header with source and destination identifiers in the second portion of the header, and transmitting the frame over an AC power line. Additionally, the patent outlines the specific encoding techniques, such as Reed-Solomon encoding and convolutional encoding, used to generate the header blocks and FEC header blocks for transmission.
