Abstract:
1. A method to adapt an error correction coding scheme, comprising: receiving a message; generating a portion of a codeword by encoding the message based on the error correction coding scheme; transmitting the message and the portion of the codeword to a receiver via a feedforward communications channel, wherein the receiver is configured to receive the transmitted portion of the codeword as a received codeword, and decode the received codeword based on the error correction coding scheme to decode the message; receiving feedback from the receiver via a feedback communications channel, wherein the feedback includes at least one portion of the received codeword; comparing the feedback to the transmitted portion of the codeword; and in response to a determination that the feedback is different from the transmitted portion of the codeword to an extent that the decoded message does not match the message, generating an additional portion of the codeword by encoding the message based on the adapted error correction coding scheme, wherein the additional portion of the codeword includes the adapted symbols of the adjusted amplitude.
