Abstract

We consider a scenario with multiple radio sources performing packet based transmissions. Each source is characterized by its power spectral density and on/off activity sequence.We propose to use a network of sensors for performing radio scene analysis. Each sensor computes the spectrogram of the received signal with a certain time and frequency resolution. Spectrograms from different sensors are collected and arraigned in a three-way array whose three dimensions correspond to space, time, and frequency indices.We propose an algorithm that recovers sources to sensors channel gain coefficients, power spectral densities and on/off activity sequences of the sources from the observed three-way array. Recovery process is illustrated with simulation examples involving 802.11b/g sources.
