Abstract: A device is disclosed. The device may include an input buffer to receive a first low bit width message. A reconstruction circuit may implement a reconstruction function on the first low bit width message, producing a first high bit width message. A computation circuit may implementing a computation function on the first high bit width message, producing a second high bit width message. A quantization circuit may implementing a quantization function on the second high bit width message, producing a second low bit width message. A decision buffer may then store the second low bit width message. The reconstruction function and the quantization function may vary depending on an iteration and a layer of the device.

Abstract: A method and a system are provided in which a message is encoded, by a neural encoder, to generate a codeword having a first length corresponding to a first code rate of the neural encoder. A number of components of the codeword corresponds to the first code rate. At least one of repeating the components or puncturing at least one of the components is performed to generate a rate-matched codeword having a second length corresponding to a second code rate. The rate-matched codeword is estimated and modified to generate an estimated codeword having the first length corresponding to the first code rate of a neural decoder. The estimated codeword is decoded, by the neural decoder, to generate an estimated message.
