SYSTEM AND METHOD OF IMPLEMENTING A COGNITIVE RADIO DEVICE WITH ENHANCED SPECTRUM SENSING
First Claim
Patent Images
1. A system for implementing a cognitive radio band device with enhanced spectrum sensing, comprising:
- a variable resolution geo-location server that receives geo-location information from the cognitive radio band device, translates the geo-location information into a location indicator, and returns the location indicator to the cognitive radio band device;
a cognitive radio band spectrum database front end that receives the geo-location indicator from the cognitive radio band device and uses the location indicator to compile an available spectrum map that is returned to the cognitive radio band device; and
a spectrum sensor available to the cognitive radio band device, the spectrum sensor being adapted to detect certain cognitive radio band signal types.

Abstract
A cognitive radio band device uses information gleaned from a database inquiry based on geo-location information in combination with spectrum sensing to determine if cognitive radio channels are available for unlicensed use.

6. A cognitive radio band device, comprising:
-
a spectrum sensor adapted to sense certain cognitive radio band signal types; memory for storing geo-location information; memory for storing an operating/backup channel list; and cognitive radio spectrum management logic that comprises program instructions adapted to communicate with the spectrum sensor and access the geo-location information and operating/backup channel list in the memory. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of enhancing spectrum sensing by a cognitive radio band device, comprising:
-
providing a variable resolution geo-location server with geo-location information available to the cognitive radio band device; receiving a location indicator from the variable resolution geo-location server; passing the location indicator to a cognitive radio spectrum database front end to request a available spectrum map from the cognitive radio spectrum database front end; and inspecting the available spectrum map to prepare a sensing map for a spectrum sensor of the cognitive radio band device. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
