Consider a variable-length feedback code with $M=2^K$ messages, target error probability $P_e$, expected decoding time $\mathbb{E}[T]$, rate $\overline{R}$, channel capacity $C$, f…

Let the system be the AWGN channel with noisy feedback described in the paper, with blocklength $N$, feedback-noise variance $\sigma^2$, signal-to-noise parameter $\gamma$, power p…
