Information reuse in dynamic spectrum access [PDF]

open access: yes, 2013
Dynamic spectrum access (DSA), where the permission to use slices of radio spectrum is dynamically shifted (in time an in different geographical areas) across various communications services and applications, has been an area of interest from technical ...

Non-Markovianity through Accessible Information [PDF]

open access: yesLatin America Optics and Photonics Conference, 2014
The degree of non-Markovianity of quantum processes has been characterized in several different ways in the recent literature. However, the relationship between the non-Markovian behavior and the flow of information between the system and the environment through an entropic measure has not been yet established.

Three-Dimensional Adaptive Modulation and Coding for DDO-OFDM Transmission System

open access: yesIEEE Photonics Journal, 2017
We propose a 3-D adaptive loading algorithm (ALA), which can individually allocate proper modulation formats, power levels, and the forward error correction codes to each orthogonal frequency division multiplexing (OFDM) subcarrier according to the ...

Molecular access to multi-dimensionally encoded information [PDF]

open access: yes, 2019
Polymer scientist have only recently realized that information storage on the molecular level is not only restricted to DNA-based systems. Similar encoding and decoding of data have been demonstrated on synthetic polymers that could overcome some of the ...

Joint Carrier Frequency Offset and Phase Noise Estimation Based on Pseudo-Pilot in CO-FBMC/OQAM System

open access: yesIEEE Photonics Journal, 2019
A simple method based on a designed pseudo-pilot is proposed for both carrier frequency offset (CFO) and phase noise (PN) estimation for the coherent optical offset-quadratic-amplitude modulation (QAM) based filterbank multicarrier (CO-FBMC/OQAM ...
