Response of noise-amplifier flows: From linear control to nonlinear jet breakup

Isha Shukla

Among hydrodynamically unstable flows, the amplifier-flows are characterized by their large amplification potential in presence of external noise. Since amplifiers do not have an intrinsic dynamics, a chosen forcing can be applied to eventually control the ...

Digital Predistortion of Power Amplifier Non-Linearities for Full-Duplex Transceivers

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Andrew Charles Mallory Austin

Non-linearities introduced by the power amplifier stage can significantly reduce the performance of self-interference cancellation in full-duplex transceivers. Accordingly, we propose a full-duplex system architecture that predistorts the digital baseband ...
