Abstract:
1. A frequency resource allocation system for a wireless network that comprises one or more unlicensed cognitive devices that operate using white spaces in a TV frequency spectrum and one or more licensed incumbent devices that are associated with an incumbent service that uses the TV frequency spectrum, comprising: one or more resource user devices comprising the one or more unlicensed cognitive devices; one or more frequency resource databases that store one or more frequency band lists, each frequency band list comprising one or more frequency bands within the TV frequency spectrum; a merit generator that: collects merit-related information specific to a location associated with the wireless network, a specified frequency band being chosen based on the merit-related information, transforms the merit-related information into different merit classes, each merit class associated with one or more frequency bands, and determines a quality measure associated with a frequency band by combining the different merit classes using a fusion method comprising at least one of Dynamic Classifier Selection (DSC), Classifier Structuring and Grouping (CSG) and Hierarchical Mixture of Experts (HME) methods, a higher quality measure indicating an unlicensed cognitive device operating in the frequency band generates less interference to the incumbent service than another frequency band associated with a lower quality measure; and a resource allocator that notifies a resource user device to operate in the specified frequency band.
