This talk compares the performance of two types of variable-length feedback coding schemes in the short-blocklength regime, decision feedback and information feedback. In both cases, we demonstrate that tail-biting convolutional codes can deliver rates surpassing the random-coding lower bound at blocklengths less than 100 bits. The decision-feedback scheme uses the reliability-output Viterbi Algorithm to determine when to stop transmission, which requires only a single bit of feedback (ACK/NACK) after each decoding attempt. In contrast, a two-phase, information-feedback scheme employs incremental redundancy and uses feedback of the received symbols to confirm or reject the decoder's tentative estimate. Finally, we discuss the implications of these schemes when used in practical systems.
