A software-defined radio system, or SDR, is a radio communication system where components that have been typically implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.
) are instead implemented by means of software on a personal computer or embedded system
.
What exactly is an SDR?Slide4
A basic SDR system is comprised of:
Personal Computer equipped
with a
Sound Card
RF Front End (the SDR)
Software to configure/operate the SDR
Signal processing is managed by the computers processor, unlike a traditional radio where dedicated components perform the same functions. This methodology provides the means to operate using varying frequencies, protocols, and environments extending the life and usefulness of the system over conventional radio hardware.
