Software Defined Radio
A Software Defined Radio (SDR) is a radio communication system where traditionally hardware components, such as mixers, filters, and modulators, are implemented in software. This allows the radio to be easily reconfigured or reprogrammed to support different radio standards, frequencies, or waveforms.
TECHNICAL DEFINITION
A Software Defined Radio (SDR) is a flexible wireless communication system that employs software-programmable digital signal processors and reconfigurable hardware (e.g., FPGAs) to implement physical layer functions, enabling dynamic adaptation to diverse military waveforms, modulation schemes, and spectrum environments for applications like electronic warfare (EW), signals intelligence (SIGINT), and secure tactical communications.
BACKGROUND
Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware are instead implemented by means of software on a computer or embedded system.
