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

Abstract—Relay cooperation has been recognized as an important mechanism to enhance connectivity and throughput in multi-hop wireless networks, especially under varying channel c...
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...
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, ...
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...
