Abstract: In case of Quadrature amplitude modulated (QAM) transmission, the residual carrier affects the quality of the received signal. We show that the carrier tracking problem is equivalent to a ...
Puzzling effects Two quantum simulations have revealed unexpected behaviour at quantum phase transitions. (Courtesy: Shutterstock/Inna-Bigun) Unexpected behaviour at phase transitions between ...
In order to accurately describe the equivalent model of shale reservoir, a series of parameters such as crack density, porosity, crack aspect ratio, fluid saturation, and time scale of ... 5A–C show ...
