Abstract :
This Higher-order statistics is widely used in radar, communication, and biomedicine and fault diagnosis. The bispectrum is not sensitive about Gaussian white noise. At the same time, the bispectrum is also not sensitive about high dynamic and low SNR. In this paper, the method of higher-order statistics is used to detect the weak signal in high dynamic and low SNR to prove the great performance under such conditions. Experiment results under different dynamic and SNR conditions in this paper show the great performance.
