DVB-T Spectrum Sensing for Federated Learning

These files contain measurement results achieved in the following scenario:Rohde&Schwarz SMBV100A signal generator transmits OFDM signal (center frequency 2000.0 MHz) with different amplifier gain.A single PC with GNU Radio and connected USRP receives a signal with a central frequency of 2000 MHz (filtered 8 MHz bandwidth). Received is set in six different positions (location of sensors presented on the figure "position.png") - creating 6 files - and collects data to detect the presence of a transmitted signal. Data that can be found in the files is stored in CSV format to be easily analyzed in ML models. Data collected during this experiment contains:- column with average received power in the analyzed channel (in mW)- column with autocorrelation value- column with decision metric (calculated as maximum eigenvalue divided by minimum eigenvalue - look below)- 8 columns with eigenvalues of the Pearson correlation matrix (8 subsequent vectors of 32768 samples)- column with information about signal transmission (label; 0 - noise, 1 - signal transmitted)
