Simulation of moderate time-scale Dynamic Spectrum Access with wide-area spectrum sensors

Simulation approaches and results are provided for Dynamic Spectrum Access (DSA) with remote wide-area spectrum monitoring equipment and moderate delay in spectrum data dissemination. Issues expected to arise using this approach include information delay time, failure to detect all transmitters, transmitter location errors, poor transmit-power estimates, and errors in the propagation model used to predict radio interference. The system works well if delays do not exceed 10 minutes, location error standard deviations are less than or equal to 2 km, and at least half of the transmitters are detected. It is found to be more sensitive to poor transmitter power and propagation-loss estimates.
