Up to date CFP: https://jmfriedt.free.fr/fosdem.html The Radio-Frequency Digital Signal Processing (RF DSP) devroom is being organized for the 2027 FOSDEM held in Brussels (Belgium) Sunday Jan. 31, 2027. The radio-frequency digital signal processing devroom is 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, * direction of arrival analysis, * interference (spoofing/jamming) detection and cancellation, * ... and all fields where the availability of the raw IQ stream representative of the electromagnetic wave characteristics, collected from single or multiple antennas, is used. Development and use of software frameworks easing such applications including GNU Radio, FutureSDR, Pothosware or custom frameworks are welcome. Novel open-hardware description, possibly including the latest acceleration peripherals including FPGA and GPUs (or others), is encouraged, especially if using FOSS frameworks. Expected presentation duration: 15 to 30 minutes. Proposals should be submitted through https://pretalx.fosdem.org/fosdem-2027/ by December 1st 2026 at latest.
