The presence detection of communication signals is the precondition and basis of information retrieval, which plays an important role in the signal processing. A new algorithm based on the fluctuation of the correlation function of the received signals in time domain is proposed. The algorithm, employing the first-order fluctuation function of the correlation function as the detection function and combining with the SDM-based adaptive threshold estimation method also proposed in this paper, provides an effective solution to the detection problems of short burst or short burst-interval signals.
