- W2377198534 abstract "In interception of the non-cooperation communication,a new effective method based on the parallel filter banks and high-order cumulants was proposed for spread spectrum signal detection. The filter banks split the input signal into many narrow frequency bands,which not only can completely descript unknown signals in the time-frequency domain,but improve the signal-to-noise ratio (SNR). Moreover,Gaussian noises can be suppressed using the three-order cumulants,which can preserve more useful information and boost the detection performance. Then parameters of the unknown signal were obtained by creating the feature matrix. The simulation indicates that it is effective for this technique to detect the direct sequence spread spectrum (DS-SS) signal and estimate the carrier frequency and the bandwidth under low SNR." @default.
