Diversity-Multiplexing Tradeoff in the Low-SNR Regime [PDF]

open access: yes, 2011
An extension of the popular diversity-multiplexing tradeoff framework to the low-SNR (or wideband) regime is proposed. The concept of diversity gain is shown to be redundant in this regime since the outage probability is SNR-independent and depends on ...

Correlated multiplexity and connectivity of multiplex random networks [PDF]

open access: yesNew Journal of Physics, 2012
Nodes in a complex networked system often engage in more than one type of interactions among them; they form a multiplex network with multiple types of links. In real-world complex systems, a node's degree for one type of links and that for the other are not randomly distributed but correlated, which we term correlated multiplexity.

Orthogonal Chirp Division Multiplexing [PDF]

open access: yesIEEE Transactions on Communications, 2016
Chirp waveform plays a significant role in radar and communication systems for its ability of pulse compression and spread spectrum. This paper presents a principle of multiplexing a bank of orthogonal chirps, termed orthogonal chirp-division ...

Integrated circuits based on broadband pixel-array metasurfaces for generating data-carrying optical and THz orbital angular momentum beams

open access: yesNanophotonics, 2023
There is growing interest in using multiple multiplexed orthogonal orbital angular momentum (OAM) beams to increase the data capacity of communication systems in different frequency ranges. To help enable future deployment of OAM-based communications, an

Electric-field multiplexing/demultiplexing of volume holograms in photorefractive media [PDF]

open access: yes, 1993
We propose a new method of volume hologram multiplexing/demultiplexing in noncentrosymmetric media. Volume holograms may be multiplexed by tuning the material parameters of the recording medium (such as refractive index or lattice parameters) while ...

A wide-band perfect light absorber at mid-wave infrared using multiplexed metal structures [PDF]

open access: yes, 2012
We experimentally demonstrate a wide band near perfect light absorber in the mid-wave infrared region using multiplexed plasmonic metal structures. The wide band near perfect light absorber is made of two different size gold metal squares multiplexed on a thin dielectric spacing layer on the top of a thick metal layer in each unit cell.

Mesoscopic Structures Reveal the Network Between the Layers of Multiplex Datasets [PDF]

open access: yesPhys. Rev. E 92, 042806 (2015), 2015
Multiplex networks describe a large variety of complex systems, whose elements (nodes) can be connected by different types of interactions forming different layers (networks) of the multiplex. Multiplex networks include social networks, transportation networks or biological networks in the cell or in the brain.

End-to-End Joint Antenna Selection Strategy and Distributed Compress and Forward Strategy for Relay Channels

open access: yes, 2009
Multi-hop relay channels use multiple relay stages, each with multiple relay nodes, to facilitate communication between a source and destination. Previously, distributed space-time codes were proposed to maximize the achievable diversity-multiplexing ...
