Abstract

A method and transceiver for determining spectrum availability within a give area is disclosed. The given area includes cells in a grid. A belief evaluator receives a measurement from a signal and assigns an instantaneous belief indicator, an instantaneous disbelief indicator and an instantaneous ignorance indicator based on a detection threshold and the power level of the measurement. The indicators quantify the probability of a presence of a transmitter within the grid cell. A belief accumulator uses the instantaneous indicators along with accumulated belief, disbelief and ignorance indicators from previous measurements to determine cumulative belief, disbelief and ignorance indicators. The accumulated belief, disbelief and ignorance indicators are the results of previous measurements and belief/disbelief/ignorance determinations for the grid cell. An allocator indicates the status of the grid cell and whether a spectrum is available. If a spectrum is available, then the grid cell is added to other available cells within the area to generate the spectrum hole.
