Deep extended feedback codes

A new Deep Neural Network (DNN)-based error correction encoder architecture for channels with feedback, called Extended Feedback (DEF), is presented in this paper. The the DEF transmits an information message followed by a sequence of parity symbols which are generated based on as well observations past forward channel outputs sent to transmitter through feedback channel. codes generalize Deepcode several ways: output over longer time intervals order provide better capability; and high-order modulation formats deployed so achieve increased spectral efficiency. Performance evaluations show that have performance compared other DNN-based feedback.
