Optimal memoryless relays with noncoherent modulation
Abstract—We derive optimal memoryless relays using noncoherent modulation over additive white Gaussian noise (AWGN) channels with or without fading. The derivation is flexible, ...

Sum-rate maximization of two-way amplify-and-forward relay networks with imperfect channel state information
Considering a two-way amplify-and-forward (AF) relay network and aiming to simultaneously maximize the two users’ mutual information lower bounds in the presence of channel esti...

A Case For Amplify-Forward Relaying in the Block-Fading Multi-Access Channel
This paper demonstrates the significant gains that multi-access users can achieve from sharing a single amplify-forward relay in slow fading environments. The proposed protocol, ...

Cross-Layer Link Adaptation Design for Relay Channels with Cooperative ARQ Protocol
The cooperative automatic repeat request (C-ARQ) is a link layer relaying protocol which exploits the spatial diversity and allows the relay node to retransmit the source data pac...
