WISCANet - Easy Radio Networks with GNURadio(and friends)
summary
WISCANet configures and runs multi-node SDR experiments from GNURadio, Python, or MATLAB with minimal setup, using GPS time sync (moving toward alternatives), Docker deployment, and mixed USRP fleets. It demonstrates multi-channel phase coherence across X310s for distributed beamforming, implements a control loop that chunks frames for offline processing, inverts a 200x200 matrix inversion in MATLAB for an MMSE beamformer, and shows real OTA results (hello packets, n^2 gain and interference rejection). Code is on GitHub.
