Cognitive Successive Interference Cancellation for Multi-User Visible Light Communication Systems

open access: yesJurnal Elkomika
Wireless communication technology continues to face challenges in meeting high bandwidth demands and the capability to serve numerous users. One promising solution is the non-orthogonal multiple access (NOMA) scheme, particularly through the use of power

Ultrasound Activated Piezoelectric Dural Patches to Drive Endogenous Neural Stem Cell–Mediated Repair Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
This study presents a wireless, non‐invasive strategy for neural repair by developing a biodegradable piezoelectric dural patch that, under transcranial ultrasound, generates localized electrical fields to drive endogenous neural stem cells toward neuronal differentiation and functional integration.

Joint User Scheduling and Power optimization in Full-Duplex Cells with Successive Interference Cancellation

open access: yes, 2017
This paper considers a cellular system with a full-duplex base station and half-duplex users. The base station can activate one user in uplink or downlink (half-duplex mode), or two different users one in each direction simultaneously (full-duplex mode).

Magnetoelectric Nanoparticle‐Based Wireless Brain–Computer Interface: Underlying Physics and Projected Technology Pathway

open access: yesAdvanced Science, EarlyView.
Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

Application of ZigZag Decoding in Frameless ALOHA

open access: yesIEEE Access, 2019
As ZigZag decoding (ZD) can resolve a collision between two packets, the combination of ZD and successive interference cancellation (SIC) is expected to provide a lower packet loss rate (PLR) and higher average throughput than the conventional frameless ...

Robust Successive Compute-and-Forward over Multi-User Multi-Relay Networks

open access: yes, 2016
This paper develops efficient Compute-and-forward (CMF) schemes in multi-user multi-relay networks. To solve the rank failure problem in CMF setups and to achieve full diversity of the network, we introduce two novel CMF methods, namely, extended CMF and

A Method in Computing Successive Interference Canceller

open access: yesJournal of Wireless Networking and Communications, 2012
Successive Interference Canceller is a multistage approach that sequentially recovers each user from the re- ceived signal. Each stage provides an estimate using the MF detector. The re-modulated signal is subtracted from the original signal and the difference signal becomes the input.

Gecko‐Like Multi‐Directional High‐Power Magneto–Mechano–Electric Energy Harvesters for Self‐Powered, Hundred‐Meter‐Scale LoRa Communication

open access: yesAdvanced Science, EarlyView.
Gecko like multi directional high power magneto mechano electric energy harvester (MME EH) for self powered, hundred meter scale LoRa communication. Inspired by the symmetric and flexible limb motion of geckos, the biomimetic harvester enables coordinated bending twisting responses to weak, low frequency (50/60 Hz) stray magnetic fields from power ...

Reconfigurable Spoof Plasmonic Skyrmion Electronics for Deformation‐Invariant Multimode Sensing

open access: yesAdvanced Science, EarlyView.
A flexible multimode sensor based on capacitively loaded spoof plasmonic skyrmions enables deformation‐invariant dielectric sensing with ultra‐compact size and high Q‐factor. Near‐equidistant resonances remain stable under shape change and bending, while capacitor loading improves bending robustness and multimode sensitivity, highlighting strong ...
