The invention discloses a method for cognitive radio system selection interception node, the radio system comprises a plurality of base stations, a plurality of user station equipment, base station as a decision node, the customer premises equipment as an interception node; the method comprises the following steps: N information statistics of all decision nodes interception interception node, and according to the correlation of the listener the information of packet interception node; and at this stage according to all the information to make the interception interception node detection decision; each packet interception node, select at least one interception node as head interception node do P information feedback to the decision node; decision feedback information interception node according to data fusion group head interception node selected make judgment, detection. The invention provides an interception mechanism CPEs history interception information statistics based on correlation, to reduce the number of CPEs is involved in feedback, which can reduce the detection probability and false alarm probability does not improve, and effectively reduce the amount of feedback.
