Description
Dynamic SOPs collection employing SDR (HackRF-ONE)
Software Defined Radio (SDR) technology serves as a multimode transceiver, enabling a programmable radio
platform. The HackRF One is an example of SDR, with the ability to scan the frequency spectrum of 30 MHz – 6
GHz and can be programmed as an FM receiver/transmitter or a simple spectrum analyzer (Figure 1a). HackRF
One provides an affordable solution in comparison to an expensive spectrum analyzer. HackRF One requires
Linux operating systems (Ubuntu utilized in this work) and is programmable employing GNU Radio Companion
(GRC – a graphical block diagram interface) or Python (HackRF sweep).

The SDR allows a system designer to develop an intelligent radio system with various purposes. The conceptual
layer over SDR is defined as Cognitive Radio (CR). It is a layer enabling the user to program the SDR based on
the application requirements. The level of self-awareness defines the intelligence of the CR to the environment
and user requirements. An essential operation in wireless sensing is determined as Dynamic Spectrum Access
(DSA), the real-time alignment of frequency spectrum utilization in response to varying environmental conditions
and objectives.
