On Channel Output Feedback in Deterministic Interference Channels [article]

Achaleshwar Sahai and Vaneet Aggarwal and Melda Yuksel and Ashutosh Sabharwal
2009 arXiv   pre-print
In this paper, we study the effect of channel output feedback on the sum capacity in a two-user symmetric deterministic interference channel.  ...  Surprisingly, we find that there is no gain in sum-capacity with feedback in a half-duplex feedback model when interference links have more capacity than direct links.  ...  Moreover, we find that when the feedback resources are symmetric and time shared with the forward channel, channel output feedback does not increase the sum capacity in a deterministic interference channel  ...

Two-Way Networks: When Adaptation is Useless

Zhiyu Cheng, Natasha Devroye
2014 IEEE Transactions on Information Theory  
In all cases we permit all nodes to adapt channel inputs to past outputs (except for portions of the linear deterministic two-way IC where we only permit 2 of the 4 nodes to fully adapt).  ...  For these deterministic models we obtain the capacity region for the two-way multiple access/broadcast channel, the two-way Z channel and the two-way interference channel (IC).  ...  Linear Deterministic Two-Way IC The two-way linear deterministic interference channel is defined by the input/output equations in Fig. 2(c) .  ...
