Call for Participation: SDR/DSP Devroom at FOSDEM 2026

The Software Defined Radio / Digital Signal Processing (SDR/DSP) devroom is being organized for FOSDEM 2026, held in Brussels, Belgium, on Sunday, February 1, 2026.

We are seeking contributions discussing free and open-source software (FOSS) for discrete-time digital signal processing and software-defined radio (SDR). Topics of interest (RF and non-RF) may include:

• Digital communication and data integrity (CRC calculation, Forward Error Correction - FEC)
• Communication channel characterization
• Navigation and positioning
• Target ranging and velocity measurement
• Signal characteristic extraction from raw IQ data (single or multiple antennas)
• 5G/6G/FutureG
• AI-enabled communications and signal processing
• Software frameworks supporting these applications, including GNU Radio, FutureSDR, Pothosware, or custom/novel frameworks

We also welcome presentations on open-hardware designs - especially those leveraging FPGAs, GPUs, or other accelerators - using FOSS tools. Demonstrations of how RF-grade oscilloscopes can function as discontinuous-stream SDR receivers would be one such example.

🗓 Proposal deadline: November 15, 2025
💻 Submit via: FOSDEM Pretalx

Join us in Brussels to share your work and advance the state of open SDR and DSP!
