Abstract: Automatic modulation classification (AMC) is an impressive technology, which is widely used in military and civilian fields. Recently, deep learning-based AMC (DL-AMC) methods have shown ...

Modulation: FSK (F3C) Emission code: 3K00F3C FSK Carrier: 1900 Hz Shift: White +400 Hz, Black -400 Hz Scan line frequency: 2 lines per second (120 lines per minute) Scan line stability: Within 5 parts ...

Self-built synthetic dataset and publicly available dataset are used. The self-built dataset is generated by Numpy, named "SIGNAL-8". It contains eight different radar signal types and can be split ...

Radios were once big complicated appliances, full of warm valves and paper-wrapped capacitors, all humming and glowing to capture signals from the aether and spit them out of a speaker. Every ...

Microwave photonics, which brings together the worlds of radiofrequency engineering and optoelectronics, has attracted great interest from both the research community and the commercial sector over ...

Unfortunately most of these use Single Side Band (SSB) as opposed to the Amplitude Modulation (AM) used by broadcasters, which cannot be received on cheap domestic SW radios. Wow the engineering world ...

This document is aimed at the Arduino developers, radio experimenters, hobbyists and anyone interested in building a receiver based on the Si473X IC family from Silicon Labs. This project is about an ...

Chronic cough (CC) is common, predominantly affecting middle-aged females. Sufferers experience significantly impaired quality of life (QoL). Cough is associated with increased healthcare costs.
