Spectrogram (waterfall display) of an Olivia 16/500 signal centered on 7073.25 kHz Olivia MFSK is an amateur radioteletype protocol, using multiple frequency-shift keying (MFSK) and designed to work in difficult (low signal-to-noise ratio plus multipath propagation) conditions on shortwave bands.
WSPR (pronounced "whisper") is an acronym for Weak Signal Propagation Reporter.It is a protocol, implemented in a computer program, used for weak-signal radio communication between amateur radio operators.
Waterfall plots are often used to show how two-dimensional phenomena change over time. [1] A three-dimensional spectral waterfall plot is a plot in which multiple curves of data, typically spectra, are displayed simultaneously. Typically the curves are staggered both across the screen and vertically, with "nearer" curves masking the ones behind.
UHD provides portability across the USRP product family. Applications developed for a specific USRP model will support other USRP models if proper consideration is given to sample rates and other parameters. Several software frameworks support UHD: GNU Radio is a Free/Libre toolkit that can be used to develop software-defined radios. This ...
Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]
