Method and system for optimizing the use of the radio spectrum and computer program product therefor |
摘要 |
A system for scanning a frequency spectrum to detect usage thereof includes an ultra-wideband receiver for performing the scanning, and cooperates with a spectrum usage estimator module and a radio controller unit. The spectrum usage estimator module derives from the scanning performed via the ultra-wideband receiver information as to usage of individual bands in the frequency spectrum. The radio controller unit controls operation of a radio cognitive system as a function of the information as to usage of individual bands in the frequency spectrum as derived by the spectrum usage estimator module. The radio cognitive system operates over unused bands in the frequency spectrum. |

1. A method of scanning a frequency spectrum to detect usage thereof, the method comprising:
performing the scanning via an ultra-wideband (UWB) receiver; deriving from the scanning, information on usage of individual bands in the frequency spectrum, the information including usage patterns in a time domain; controlling operation of a radio cognitive system based upon the information for operating the radio cognitive system over unused bands in the frequency spectrum; and verifying whether a signal received over a certain band is noise or a signal corresponding to spectrum usage, the verifying comprising comparing the signal received over the certain band with at least one reference value and comparing the signal received over the certain band with relative signal strength peaks in adjacent bands, the at least one reference value being retrieved from a table of references values, the references values being associated with respective signal types and frequency bands in the frequency spectrum. |
