Beamforming OFDM Performance under Joint Phase Noise and I/Q Imbalance
(
IEEE
, 2015 , Article)
Phase noise (PHN) and in-phase/quadrature (I/Q) imbalance are two major RF impairments in direct-conversion wireless transceivers. Beamforming and orthogonal frequency division multiplexing (OFDM) schemes have been adopted ...

To compare the anthropometric and lifestyle characteristics of active and inactive adolescents in Saudi Arabia and Britain. A school-based cross-sectional study was conducted at four cities in Saudi Arabia (Riyadh and ...
Poreless Separator and Electrolyte Additive for Lithium-Sulfur Batteries with High Areal Energy Densities
(
WILEY-VCH Verlag
, 2015 , Article)
Despite the attractive theoretical capacity of sulfur over 1600 mA h g−1, lithium–sulfur (Li–S) batteries suffer from insufficient cycle lives mainly due to fatal polysulfide dissolution. This chronic drawback becomes ...
Thermochemical treatment of fly ash for synthesis of mesoporous activated carbon
(
Springer Netherlands
, 2015 , Article)
A mesoporous activated carbon is produced from oil fly ash (OFA) using chemical and thermal treatments at different activation conditions. The ash samples were refluxed with a range of compositions of sulfuric, nitric, and ...
Properties of Dialkylcarbonate + 1-Alkanol Mixtures at the Vacuum Interface
(
American Chemical Society
, 2016 , Article)
The properties of solutions formed by dialkylcarbonate + 1-alkanol solutions are studied using classic molecular dynamics simulations. The effects of solution composition, temperature, and dialkylcarbonate type have been ...
