Autoři: Trillingsgaard, Kasper Fløe, Yang, Wei, Durisi, Giuseppe, 1977, Popovski, Petar
Zdroj: SWIFT : short-packet wireless information theory IEEE Transactions on Information Theory. 64(12):7719-7741
Témata: full feedback, variable-length coding, finite blocklength regime, Broadcast channel with common-message, channel dispersion
Popis: We investigate the maximum coding rate achievable on a two-user broadcast channel for the case where a common message is transmitted with feedback using either fixed-blocklength codes or variable-length codes. For the fixed-blocklength-code setup, we establish nonasymptotic converse and achievability bounds. An asymptotic analysis of these bounds reveals that feedback improves the second-order term compared to the no-feedback case. In particular, for a certain class of antisymmetric broadcast channels, we show that the dispersion is halved. For the variable-length-code setup, we demonstrate that the channel dispersion is zero.
