Mod-CL is a self-supervised contrastive learning framework for automatic modulation classification (AMC). The key idea is to exploit intra-instance modulation consistency: different temporal segments ...

Abstract: Frequency modulation is widely utilized in inductive power transfer systems and is also included in the Qi standard for low-power chargers. This brief examines small-signal modeling and ...

Abstract: The Nyquist folding receiver (NYFR) is a new ultra-wideband (UWB) sensing structure that can sense signals in an UWB space. Since linear frequency modulation (LFM) signal is widely used in ...

The Pentagon’s internal watchdog has completed a monthslong review of Secretary of Defense Pete Hegseth’s use of Signal to discuss sensitive military operations and has submitted its findings to ...
