1. A method for determining spectrum availability for a transceiver, the method comprising:

  • obtaining data from a database;

    determining a probability of a presence of a transmitter in a grid cell;

    assigning an instantaneous belief indicator, an instantaneous disbelief indicator, and an instantaneous ignorance indicator to the grid cell based at least in part upon the data obtained from the database;

    determining a cumulative belief indicator, a cumulative disbelief indicator, and an ignorance indicator using the instantaneous belief indicator, the instantaneous disbelief indicator, and the instantaneous ignorance indicator; and

    indicating spectrum availability in the grid cell based on the cumulative belief indicator, the cumulative disbelief indicator, and an ignorance indicator.
