Optimal Routing for the Gaussian Multiple-Relay Channel with Decode-and-Forward [PDF]
, 2007 In this paper, we study a routing problem on the Gaussian multiple relay channel, in which nodes employ a decode-and-forward coding strategy. We are interested in routes for the information flow through the relays that achieve the highest DF rate.

Capacity Theorems for the AWGN Multi-Way Relay Channel
, 2010 The L-user additive white Gaussian noise multi-way relay channel is considered, where multiple users exchange information through a single relay at a common rate. Existing coding strategies, i.e., complete-decode-forward and compress-forward are shown to

Transmit Signal and Bandwidth Optimization in Multiple-Antenna Relay Channels [PDF]
, 2010 Transmit signal and bandwidth optimization is considered in multiple-antenna relay channels. Assuming all terminals have channel state information, the cut-set capacity upper bound and decode-and-forward rate under full-duplex relaying are evaluated by ...

Robust Transceiver Design for Full-Duplex Decode-and-Forward Relay-Assisted MIMO Systems [PDF]
Asilomar Conference on Signals, Systems and Computers, 2019 Robust transceiver design against unresolvable system uncertainties is of crucial importance for reliable communication. For instance, full-duplex communication suffers from such uncertainties when canceling the self-interference, since some residual ...

Mobile User Connectivity in Relay-Assisted Visible Light Communications
Sensors, 2018 In this paper, we investigate relay-assisted visible light communications (VLC) where a mobile user acts as a relay and forwards data from a transmitter to the end mobile user.

Optimal Coding Functions for Pairwise Message Sharing on Finite-Field Multi-Way Relay Channels
, 2014 This paper considers the finite-field multi-way relay channel with pairwise message sharing, where multiple users exchange messages through a single relay and where the users may share parts of their source messages (meaning that some message parts are ...

Noisy Network Coding with Partial DF
, 2015 In this paper, we propose a noisy network coding integrated with partial decode-and-forward relaying for single-source multicast discrete memoryless networks (DMN's). Our coding scheme generalizes the partial-decode-compress-and-forward scheme (Theorem 7)

Lattice Codes for the Gaussian Relay Channel: Decode-and-Forward and Compress-and-Forward [PDF]
IEEE Transactions on Information Theory, 2013 Lattice codes are known to achieve capacity in the Gaussian point-to-point channel, achieving the same rates as independent, identically distributed (i.i.d.) random Gaussian codebooks. Lattice codes are also known to outperform random codes for certain channel models that are able to exploit their linearity. In this work, we show that lattice codes may
