Overview Of SDR Platforms Based On Open Source Software: A 5G System Emulation With Open Air Interface

Τhis paper focuses on the latest trends on software defined radio platforms based on open source software and aims to highlight the benefits that these platforms offer in terms of flexibility and cost. The requirements of hardware and the special features of operating systems that enable the SDR software to run on x86-64 systems are presented in detail. Moreover an emphasis is given to the software architectures used in open source projects implementing wireless protocols. As a paradigm of an open source SDR platform we emulate a 5G system, based on Open Air Interface software and docker engine, installed on a Linux PC. Finally, the main aspects of this emulation are presented and conclusions are made.
