Multi-Way Relay Networks: Orthogonal Uplink, Source-Channel Separation and Code Design
Roy Timo, Gottfried Lechner, Lawrence Ong +1
We consider a multi-way relay network with an orthogonal uplink and correlated sources, and we characterise reliable communication (in the usual Shannon sense) with a single-letter…
Capacity Results for Two Classes of Three-Way Channels
Lawrence Ong
This paper considers the three-way channel, consisting of three nodes, where each node broadcasts a message to the two other nodes. The capacity of the finite-field three-way chann…
On Capacity and Optimal Scheduling for the Half-Duplex Multiple-Relay Channel
Lawrence Ong, Mehul Motani, Sarah J. Johnson
We study the half-duplex multiple-relay channel (HD-MRC) where every node can either transmit or listen but cannot do both at the same time. We obtain a capacity upper bound based…
On the Capacity of the Binary-Symmetric Parallel-Relay Network
Lawrence Ong, Sarah J. Johnson, Christopher M. Kellett
We investigate the binary-symmetric parallel-relay network where there is one source, one destination, and multiple relays in parallel. We show that forwarding relays, where the re…
On the Equal-Rate Capacity of the AWGN Multiway Relay Channel
Lawrence Ong, Christopher M. Kellett, Sarah J. Johnson
The L-user additive white Gaussian noise multiway relay channel is investigated, where L users exchange information at the same rate through a single relay. A new achievable rate r…
The Finite Field Multi-Way Relay Channel with Correlated Sources: Beyond Three Users
Lawrence Ong, Roy Timo, Sarah J. Johnson
The multi-way relay channel (MWRC) models cooperative communication networks in which many users exchange messages via a relay. In this paper, we consider the finite field MWRC wit…
