On Achievable Rate Regions of the Asymmetric AWGN Two-Way Relay Channel
, 2011 This paper investigates the additive white Gaussian noise two-way relay channel, where two users exchange messages through a relay. Asymmetrical channels are considered where the users can transmit data at different rates and at different power levels ...

Photoswitching Conduction in Framework Materials
Advanced Functional Materials, EarlyView.This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

Successive Decode-and-Forward Relaying With Privacy-Aware Interference Suppression
IEEE Access, 2020 Successive relaying holds the promise of achieving spatial diversity gain for single-antenna users while recovering the multiplexing loss due to the half-duplex relaying in B5G/6G.

Amplify-and-forward versus decode-and-forward relaying: which is better?
, 2012 Performance of multi-hop MIMO relay channels under the amplify-and-forward and decode-and-forward proto- cols are compared via the capacity and SNR gains. In an N - hop channel of linear topology with multi-antenna source and destination and single-antenna relay nodes, the capacity gain of the DF relaying over the AF one does not exceed log 2 N bit/s ...

KSII Transactions on Internet and Information Systems, 2019 In this paper, we propose a two-way relaying scheme using non-orthogonal multiple access (NOMA) technology. In this scheme, two sources transmit packets with each other under the assistance of the decode-and-forward (DF) relays, called as a TWDFNOMA ...

Advanced Functional Materials, EarlyView.Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Distributed Decode-Forward for Relay Networks
, 2017 A new coding scheme for general N-node relay networks is presented for unicast, multicast, and broadcast. The proposed distributed decode-forward scheme combines and generalizes Marton coding for single-hop broadcast channels and the Cover-El Gamal ...

Combining Decoded-and-Forwarded Signals in Gaussian Cooperative Channels [PDF]
2006 IEEE International Symposium on Signal Processing and Information Technology, 2006 The goal of this paper is to investigate different ways of combining signals that have been decoded- nd-forwarded by a bunch of relays. We more deeply look at the case where the relays are in bad reception conditions and the cooperation powers are sufficiently high.

Cache Aided Decode-and-Forward Relaying Networks: From the Spatial View
Wireless Communications and Mobile Computing, 2018 We investigate cache technique from the spatial view and study its impact on the relaying networks. In particular, we consider a dual-hop relaying network, where decode-and-forward (DF) relays can assist the data transmission from the source to the ...
