The term SDR (Software Defined Radio) was coined by Rohde in 1985; first official document disclosed in UK during Classified Session (USA Secret). This to achieve sufficient computational capacity, in particular for processing ultra-wideband high bit rate waveforms, within acceptable size and weight factors, within unit cost, and acceptable power consumption. SDR offers the flexibility between bandwidth and range, the ability to adapt to the environmental parameters and employ optimal wide-band pulse characteristics for channel equalization and robustness, and finally the capability to easily adapt to current communication infrastructures, such as personal computers. The UWB (Ultrawideband) technology implementation is optimized for applications such as detecting unknown signals, identifying interference, spectrum monitoring, spectrum clearance, and signal search over wide frequency ranges, producing signal content and direction finding of identified signals. This talk will show sophisticated digital signal processing implemented in all modern receivers utilizing 5G technology for the applications in IoT (internet of things) and also advantages of SDR processing for radio-monitoring will be explained.
