The following call for participation to the SDR/DSP devroom is being shared. Deadline of Nov 15 was kept on purpose since deadline extension has become the standard for conference attendees nowaday: ---------- The Software Defined Radio/Digital Signal Processing (SDR/DSP) devroom is being organized for the 2026 FOSDEM held in Brussels (Belgium) Sunday Feb. 1, 2026. We are seeking contributions discussing FOSS software for (radiofrequency) discrete time digital signal processing/software defined radio (SDR) including digital communication and data integrity (CRC calculation, Forward Error Correction -- FEC), communication channel characterization, navigation and positioning, target ranging and velocity measurement, and signal characteristics extraction from raw IQ collected from single or multiple antennas, as well as software frameworks easing such applications including GNU Radio, FutureSDR, Pothosware or custom frameworks. Novel openhardware description, possibly including the latest acceleration peripherals including FPGA and GPUs (or others), is encouraged, especially if using FOSS frameworks, but maybe also demonstrating how a radiofrequency grade oscilloscope can make an excellent (discontinuous stream) SDR receiver. Proposals should be submitted through https://pretalx.fosdem.org by November 15 at latest, or 2 weeks from now. See you in Brussels, Jean-Michel -- JM Friedt, FEMTO-ST Time & Frequency, 26 rue de l'Epitaphe, 25000 Besancon, France
