Proceedings of the 2015 Workshop on Software Radio Implementation Forum

Abstract

Last year, we talked to a thirty-six year old satellite on its way back after a wild journey through the solar system. Without the original hardware around to talk to it, a group of enthusiasts put together a software defined radio solution within weeks to reopen our communications with the ICE-3/ISEE-3 satellite. Using the open source GNU Radio software and an Ettus Research software radio frontend, they plugged into the Arecibo Observatory, the world's largest singleaperture radio telescope, and began talking. Software radio had done something we could not have done any other way given the time constraints on the window of opportunity. The team of engineers and scientists that did this showed us the power and flexibility of what we have achieved in software radio. But the promise of SDR is not just in its malleability. We are looking to the future of communications and the next great ideas. SDR blends the physics of radio, the math of signal processing, and the innovation of computer science. The merging of these domains opens up possibilities in performance and crosslayer development that will extend into new ways of thinking about communications and platforms. The Software Radio Implementation Forum (SRIF) encompasses the academic pursuit of understanding the possibilities and limitations of software radio technology. The papers, posters, and demos shown over the past three years and those of this current year are working on new ways take advantage of software radio. In the agenda for SRIF'15, the authors will present how to enhance software radio with innovations in computer processors, explore applications spaces for what new capabilities with which we are now presented, and looking at how the spanning of computer and radio hardware and software leads to new ways of doing cross-domain work. In the latter, we see work both in cross-layer optimization as well as utilizing different levels of the computer architecture to enhance our use of memory and operating system concepts. We are pleased to welcome everyone to the fourth SRIF workshop in Paris as a MobiCom workshop. We have presenters, posters, and demonstrations from all over the world selected by a strong and dedicated program committee.
