摘要

There are systems and methods for determining a threshold value for sensing of a spectrum is proposed. The systems and methods include the receiving a false alarm rate, wherein the false alarm rate with a wrong identifications by means of a coating of a segment of the spectrum is connected, determining a noise reason signal as a function of a noise factor and the properties of a mrss - (multi - resolution spectrum sensing; sensing of the spectrum with multi resolution) window and calculating a said cell can activate - threshold value, at least partially based on the false alarm rate and the noise floor. The systems and methods can also be further includes determining whether a region of an rf - (radio frequency; radio frequency) spectrum is occupied, at least partially based on the calculated said cell can activate - threshold value.
