Experimental setups for cellular communications have always been a rare commodity in academia. Although the advent of software defined radios (SDRs) made it easier for researchers to prototype their ideas on real hardware, existing SDR solutions and associated reference design codes provide only basic cellular functionality with limitations.
Thankfully, researchers from Technische Universität Darmstadt were able to demonstrate the first SDR-based testbed for in-band device-to-device (D2D) communications using LabVIEW Communications and USRP (Universal Software Radio Peripheral) hardware.
The First Experimental Testbed for In-Band D2D Communications in 5G
The experimental SDR solution was based on USRP RIO devices, the LabVIEW Communications System Design Suite, and the LabVIEW Communications LTE Application Framework.
This demonstration makes it easier for researchers in academia to freely implement their D2D proposals in an SDR testbed and observe the impact of real-world channel characteristics on the system’s performance.
