Acquiring and Sharing Knowledge for Developing SCA Based Waveforms on SDRs.

摘要

The NATO Research and Technology Organization (RTO) / Information Systems Technology (IST) Research Task Group (RTG) on Software Defined Radio (SDR), works on the issues concerning SCA based implementations of waveforms on SDRs. This paper gives a review of the motivation, workflow and results of this international working group. With a potential target of building a Waveform Library in the future, it is important that all the partner nations collaborate and work together. In our contribution, we present some of the important results achieved by national research labs in Germany (FKIE), Turkey (TUBITAK), and Norway (FFI) during the tenure of this Group. Firstly, we present the SCA- based implementation results of STANAG 4285 waveform and the effect of increasing the granularity of the SCA waveform application on the system overhead. After that, we show the portability approach taken to port a waveform between different Operating Environments (OEs) and platforms. The portability efforts between the partner nations are also presented. Finally, the interoperability results show how a waveform running on two different OEs of different partner nations is still able to exchange data.
