GRCon 2021 celebrates and showcases the substantial and remarkable progress of GNU Radio over the past two decades. We invite developers and users from the GNU Radio community to present your projects, presentations, papers, posters, and problems at GNU Radio Conference 2021.

We invite developers and users from the GNU Radio Community to present your projects, presentations, papers, posters, and problems at GNU Radio Conference 2021. Submit your talks, demos, and code!

## Submitting

You may make one or more submissions under the following categories for presentation at GRCon. In addition to submitting a presentation, you may submit a paper to the Technical Proceedings of GRCon21. You do not need to submit a paper to the Proceedings in order to present at GRCon.

We request that papers are formatted according to this LibreOffice Template or LaTeX class.

Talks are 30 minutes long, including 5 minutes reserved for audience questions. Each presentation should be a slide-deck that can be shared publicly (PDF) after the conference. Real-world results using GNU Radio and hardware will be favored over simulation-only work.

Talks will be recorded and published on the GNU Radio YouTube channel after the conference.

Papers can be submitted with or without a talk. Authors are encouraged to attend the conference, but it is not a requirement for paper acceptance. Detailed real-world results using GNU Radio are encouraged.

Workshops are 1–4 hours long, and should have an educational or “How-To” approach, with a large hands on portion. If slides are used, they should be publicly shareable (PDF) after the conference.

Lightning Talks are very concise (4-5 minutes), talks on topics of high interest to GNU Radio users and developers, and provide a chance for new presenters to share their use cases, projects or demos.

Posters can display any type of material that you believe is interesting to the community, and while most posters are technical, they don’t have to be.

## Dates

First round closes 1 May 2021. Final round closes 1 September 2021.

All contributions submitted by 1 May 2021 will get a final decisions of acceptance by 14 May 2021.

All contributions submitted between 1 May and 1 September will be accepted/rejected on a rolling basis. We do not guarantee a notification deadline for submissions after 1 May. Submissions for presentations may close sooner than 1 September if all available speaker slots are taken.

If you have questions or need assistance with the submission system, or have content that doesn’t quite fit and you want to talk it over, please write grcon@gnuradio.org.

If your submission is accepted, you must register for the conference or your talk will be dropped from the schedule. Please use the speaker registration in this case in order to lock in the regular price.

Please note that submitting a paper to the Technical Proceedings is not required to submit a Talk, Tutorial, or Poster, but is strongly encouraged. You also do not need to attend the conference to publish in the Technical Proceedings.
