| Abstract |
We present achievable error exponent regions for the Two-Way AWGN channel under an expected block power constraint and variable-length coding (VLC). We propose an achievability scheme that allows terminals to cooperate via interaction to detect decoding errors and request re-transmissions. Under this scheme, in certain rate-pair regimes both directions are able to simultaneously attain error exponent pairs larger than the feedback-free point-to-point random coding error exponents.
