In the double-threshold spectrum sensing algorithm, if the energy value received by the cognitive vehicle user is less than threshold value λ 1 , the local judgment result is H 0 . If the energy value received by the cognitive vehicle user is greater than threshold value λ 2 , the local judgment result is H 1 .
