A Full-Duplex Diversity-Assisted Hybrid Analogue/Digitized Radio Over Fibre for Optical/Wireless Integration

open access: yes
A duplex Radio Over Fibre (ROF) ring architecture is proposed taking into account the constraints imposed by the cost of fibre laying and of the optical/electronic components, as well as the spectral efficiency and the duplex link performance.

Dual‐Channel Interdigitated Aptamer‐Based Sensors for Rapid Small‐Molecule Detection in Biofluids

open access: yesAngewandte Chemie International Edition, EarlyView.
An electrochemical aptamer sensing chip employs dual interdigitated electrodes and selective self‐assembled monolayer removal to convert small‐molecule recognition into robust “signal‐off/on” responses. This dual‐channel signal conversion minimizes background noise and accelerates probe diffusion, enabling rapid (as fast as 5–30 min), low‐volume ...

Full-duplex relaying with self-interference avoidance

open access: yes, 2014
Transmettre et recevoir des signaux simultanément (communication full-duplex) sur la même bande de fréquence n'est possible que grâce à la prévention de l'auto-interférence avant d'atteindre le convertisseur analogique numérique de l'antenne de réception.
