Operating half-duplex diamond networks with two interfering relays

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

This paper considers a diamond network with two interfering relays, where the source communicates with the destination via a layer of 2 half-duplex relays that can communicate with each other. The main focus is on characterizing the 3 relay receive/transmit configuration states (out of the 4 possible ones) that suffice to achieve the approximate capacity of the network. Towards this end, the binary linear deterministic approximation of the Gaussian noise channel is analyzed, and explicit scheduling and relaying schemes are presented. These schemes quantify the amount of information that each relay is responsible for sending to the destination, as well as the fraction of time each relay should receive and transmit.
