N2 - A novel interference detection algorithm based on adaptive threshold was proposed, in which the MLT (Modulation Lapped Transformation) data were used to perform interference detection processing based on double thresholds. The results show that proposed algorithm has better performance of interference detection processing, especially at high SNRs, than the other two algorithms, adaptive threshold algorithm and the traditional double-threshold algorithm. The proposed algorithm can reduce the false detection probability without interference and the detection probability of small interference at high SNRs while ensuring the detection probability of interference at low SNRs. The algorithm shows good performance of interference detection at a wide range of SNRs.
