Exploring GNU Radio - Applications

In addition to the examples discussed above, GNU Radio comes with a complete HDTV transmitter and receiver, a spectrum analyzer, an oscilloscope, concurrent multichannel receiver and an ever-growing collection of modulators and demodulators.
Projects under investigation or in progress include:
A TiVo equivalent for radio, capable of recording multiple stations simultaneously.
Time Division Multiple Access (TDMA) waveforms.
A passive radar system that takes advantage of broadcast TV for its signal source. For those of you with old TVs hooked to antennas, think about the flutter you see when airplanes fly over.
Radio astronomy.
TETRA transceiver.
Digital Radio Mundial (DRM).
Software GPS.
Distributed sensor networks.
Distributed measurement of spectrum utilization.
Amateur radio transceivers.
Ad hoc mesh networks.
RFID detector/reader.
Multiple input multiple output (MIMO) processing.
