Abstract:
1. A method of exploiting location awareness to improve communication performance in a wireless cognitive radio system, the system having at least one cognitive radio capable of obtaining its location information and at least one cognitive radio incapable of obtaining its own location information and incapable of having its location information determined by the at least one cognitive radio capable of obtaining its location information, the method comprising: determining absolute position information for the at least one cognitive radio capable of obtaining its location information; receiving digital topographical data related to the absolute position information; classifying the environment of the cognitive radio system based on the absolute position and the topographical data; matching the classified environment with corresponding statistical parameters to identify propagation characteristics of the system; disseminating the propagation characteristics of the system to the at least one cognitive radio incapable of obtaining its own location information and incapable of having its location information determined by the at least one cognitive radio capable of obtaining its location information; and improving the communication performance of the cognitive radio system by adapting the at least one cognitive radio capable of obtaining its location information and the at least one cognitive radio incapable of obtaining its own location information and incapable of having its location information determined by the at least one cognitive radio capable of obtaining its location information according to the propagation characteristics.
