BROADBAND SPECTRUM SENSING METHOD, FUSION CENTER, SENSING NODE AND SYSTEM

摘要

The present invention relates to the field of communications. Disclosed are a broadband spectrum sensing method, a fusion center (FC), a sensing node (SN) and a computer storage medium. The method comprises: the FC obtaining statistical idle probabilities of all current primary user (PU) physical channels; based on a sequence of the statistical idle probabilities from large to small, assigning SNs used for detecting channel spectrums to the PU physical channels in sequence; using the SNs assigned to the PU physical channels to detect the channel spectrums for the PU physical channels; and based on channel spectrum detection results, determining status of the PU physical channels.
