Systems and methods for determining sensing thresholds of a multi-resolution spectrum sensing (MRSS) technique for cognitive radio (CR) systems |
摘要 |
Systems and methods may be provided for threshold determinations for spectrum sensing. The systems and methods may include receiving a false alarm rate, where the false alarm rate is associated with false occupancy identifications of a spectrum segment, determining a noise floor as a function of a noise figure and characteristics of a multi-resolution spectrum sensing (MRSS) window, and calculating a sensing threshold based at least in part upon the false alarm rate and the noise floor. The systems and methods may also include determining whether a portion of an RF spectrum is occupied based at least in part on the calculated sensing threshold.
