Abstract
SDR stands for Software Defined Radio. This term encompasses programmable transceiver which supports various wireless technologies with low dependence of hardware. The main advantage of the SDR is the capability of the migration during prototypes developments from one standard based device to the other, support for many technologies (such as WiFi, LTE, 5G NR), the easy introduction of new releases with minimum hardware updates and also it deals with many software defined wireless communication protocols (e.g. PHY, MAC) rather than hardware based solutions. One of the technologies that have benefited from SDR is the mobile communications, being LTE and 5G NR technologies that are currently available, under Open Source solutions in SDR for a laboratory tests. The deployment of a SDR prototype could be key for the emerging 5G Broadcast solutions. In this article we will perform an analysis of the SDR open source platforms which offers 5G Broadcast solutions. For instance, the current OAI SDR broadcast solution and the 5G broadcast solution, recently developed by UPV and ORS, will be evaluated.
