Method and system for rate-matching auto-encoders

A method comprising:

• estimating, at an electronic device, a rate-matched codeword having a first length corresponding to a first code rate;
• modifying, by a processor of the electronic device, the rate-matched codeword to generate a codeword having a second length corresponding to a second code rate of a neural decoder, wherein a number of components of the codeword corresponds to the second code rate, the modifying comprising generating the codeword having the second length by averaging or summing values across symbols of the rate-matched codeword;
• and
• decoding the codeword, by the neural decoder of the electronic device, to generate a message.

A method comprising:

• encoding and rate-matching a first set of messages, by a rate-matched neural encoder, to generate a first set of rate-matched codewords, wherein the first set of messages comprises subsets, each subset corresponding to a different code rate;
• adding noise to the first set of rate-matched codewords to generate a second set of received codewords;
• modifying and decoding the second set of received codewords, by a rate-matched neural decoder, to generate a second set of messages;
• and
• determining an average loss between the first set of messages and the second set of messages across the different code rates;
• and
• modifying a parameter of at least one of the rate-matched neural encoder or the rate-matched neural decoder based on the average loss.

A system comprising:

• a first electronic device configured to:
• encode a message, by a neural encoder, to generate a codeword having a first length corresponding to a first code rate of the neural encoder, wherein a number of components of the codeword corresponds the first code rate;
• perform at least one of repeating the codeword or puncturing at least one of the codeword to generate a rate-matched codeword having a second length corresponding to a second code rate;
• and
• transmit the rate-matched codeword;
• and
• a second electronic device configured to:
• estimate the rate-matched codeword;
• modify the estimate of the rate-matched codeword to generate an estimated codeword having the first length corresponding to the first code rate of a neural decoder;
• and
• decode the estimated codeword, by the neural decoder, to generate an estimated message.
