Nearest Neighbour Decoding and Pilot-Aided Channel Estimation in Stationary Gaussian Flat-Fading Channels

open access: yes, 2011
We study the information rates of non-coherent, stationary, Gaussian, multiple-input multiple-output (MIMO) flat-fading channels that are achievable with nearest neighbour decoding and pilot-aided channel estimation.

On Multiple Symbol Detection for Diagonal DUSTM Over Ricean Channels [PDF]

open access: yes, 2008
This letter considers multiple symbol differential detection for multiple-antenna systems over flat Ricean-fading channels when partial channel state information (CSI) is available at the transmitter.

New OSTBC for Blind Channel Estimation and Tracking in MIMO-OFDM Systems

open access: yesJournal of Telecommunications and Information Technology, 2019
Applying orthogonal space time block coding (OSTBC) to multiple-input multiple-output (MIMO) systems helps reduce receiver complexity. However, this approach has been applied only to flat fading channels, as when the channel is a frequency selective ...

Analysing Effect of Direction of Layups to Distortions of Laminated Carbon Fibre-Reinforced Composites

open access: yesMekanika, 2020
The distortions of the laminates (flat panels and channel sections) with different stacking sequences were investigated in this lab session. There were two methods compared, measurement of the experimental specimens and prediction using classical ...

Region Adaptive Single Image Dehazing

open access: yesEntropy, 2021
Image haze removal is essential in preprocessing for computer vision applications because outdoor images taken in adverse weather conditions such as fog or snow have poor visibility.

Remote sensing of intertidal morphological change in Morecambe Bay, U.K., between 1991 and 2007 [PDF]

open access: yes, 2010
Tidal Flats are important examples of extensive areas of natural environment that remain relatively unaffected by man. Monitoring of tidal flats is required for a variety of purposes. Remote sensing has become an established technique for the measurement

First-Principles Study on Electron Conduction in Sodium Nanowire

open access: yes, 2004
We present detailed first-principles calculations of the electron-conduction properties of a three-sodium-atom nanowire suspended between semi-infinite crystalline Na(001) electrodes during its elongation.

Free Probability based Capacity Calculation of Multiantenna Gaussian Fading Channels with Cochannel Interference [PDF]

open access: yes, 2011
During the last decade, it has been well understood that communication over multiple antennas can increase linearly the multiplexing capacity gain and provide large spectral efficiency improvements.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Oscillatory flow of rheological complex fluid in a flat channel [PDF]

open access: yesE3S Web of Conferences
The article examines the oscillatory flow of rheological complex fluids in a flat channel, in which the rheological complex fluid was obtained based on the Maxwell model, and its mixture is described based on the Newtonian fluid model.
