This lecture presents SDR (software defined radio) technology and it’s emerging trends for the application in detecting unknown signals, identifying interference, spectrum monitoring, and spectrum clearance.

The SDR (Software Defined Radio) is a radio communication system where components that have been typically implemented in hardware are instead implemented by means of software on an embedded computing device. The term SDR (Software Defined Radio) using digital processing of sampled analog signals was coined by author in 1985, which is the first public software radio initiative(reported on Feb 26, 1985 as a US Classified Secret Session) [1].

SDR represents a major challenge in the design paradigm for radios in which a large portion of the functionality is implemented through programmable signal processing devices, giving the radio ability to change its operating parameters to accommodate new features and capabilities [2]-[3]. In addition to this, adequate computational capability for processing high bit-rate waveforms, within acceptable size, power consumption, cost, and weight are the critical parameters. This talk presents an overview of technologies and emerging trends that facilitated the development of SDR for the applications in hunting/detecting unknown signals, identifying interference, spectrum monitoring and clearance, signal search over wide frequency ranges, producing signal content and direction finding of identified signals, Internet of Things (IoT), Big Data, and radio monitoring systems.
