Analog network coding using differential and double-differential modulation with relay selection

ICT Express, 2019
A simple relay selection scheme is proposed for analog network coding using differential modulation (ANC-DM). We propose a relay selection scheme based solely on the received signal power in which their own information is canceled out at each source node.

On Design of Collaborative Beamforming for Two-Way Relay Networks

, 2010
We consider a two-way relay network, where two source nodes, S1 and S2, exchange information through a cluster of relay nodes. The relay nodes receive the sum signal from S1 and S2 in the first time slot.

Source-channel coding for the multiple-access relay channel [PDF]

2011 8th International Symposium on Wireless Communication Systems, 2011
This work considers reliable transmission of general correlated sources over the multiple-access relay channel (MARC) and the multiple-access broadcast relay channel (MABRC). In MARCs only the destination is interested in a reconstruction of the sources, while in MABRCs both the relay and the destination want to reconstruct the sources.

Toward Energy Efficient Electrochemical Valorization of Waste Nitrate and Sulfide

Advanced Materials, EarlyView.
This work introduces an integrated electrochemical strategy couples nitrate reduction with sulfide oxidation for energy‐efficient wastewater valorization. A Cu‐Co dual‑site catalyst, engineered for close proximity, promotes *NO2 relay and subsequently NH3 formation, enabling the system to operate at substantially reduced cell voltages and produce high ...

A joint time-invariant filtering approach to the linear Gaussian relay problem [PDF]

, 2011
In this paper, the linear Gaussian relay problem is considered. Under the linear time-invariant (LTI) model the problem is formulated in the frequency domain based on the Toeplitz distribution theorem.

Serotonergic System‐Targeted Nucleic Acid Hydrogel Coordinates Excitability Restoration and Circuit Reconstruction for Spinal Cord Injury Therapy

Advanced Materials, EarlyView.
The study reports a DNA/RNA heteroduplex hydrogel (SeroPTEN‐CG) that undergoes DNase‐mediated hydrogel‐to‐nanogel transition for spinal cord injury therapy by targeting the serotonergic system, combining 5‐hydroxytryptamine (5‐HT)‐mediated excitability restoration to reactivate dormant interneurons with phosphatase and tensin homolog (PTEN)‐targeted ...
