Let $K_A$ denote the number of mass points in a capacity-achieving input distribution for the amplitude-constrained AWGN channel with amplitude constraint $A$. Linear-growth conjec…

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…
