Hi Piotr - The error you encountered generally means that UHD was already installed in the same prefix as the build would be going into, and that the UHD API changed between the versions. Normally UHD can be build over a pre-existing install, but sometime not too long ago this feature was broken vi

Hi Ben, In case of using WiFi as signals of opportunity, we do not use directional antennas or set the reference receiver in a specific direction. Here the reference signal is the signal received from a receiver kept in Line of Sight with the main transmitter. The surveillance receiver does use a d

Hi Luca, thanks for sharing your proposal draft! Here are some remarks: 1. You list a MIMO channel model as deliverable. For slow, flat flading you can use (as you correctly stated) a simple matrix multiplication block. That, however, already exists in GNU Radio. Or were you thinking of a wra
