Arbitrarily Varying Broadcast Channel with Uncertain Cooperation
Uzi Pereg, Yossef Steinberg · Repository for Publications and Research Data (ETH Zurich) · 2020
In this work we study the arbitrarily varying physically degraded broadcast channel with cooperating decoders, with high degree of uncertainty in the network model: the channel statistics is arbitrarily varying, and the cooperation link is not reliable, as its existence is not guaranteed a priori.We construct a coding scheme that can cope with the arbitrarily varying nature of the channel, and with the cooperation link uncertainty.Inner and outer bounds are developed on the capacity region of this channel, and conditions are suggested under which the bounds coincide, thus characterising the capacity region of this model.
