New signal detection method combining higher order cumulant with matched filter
Kui Zhang · Systems engineering and electronics · 2006
To consider space weak signal detection in communications recon,a new signal detection method based on High-Orde Cumulant associated with matched filter is presented.On the basis of classical likelihood ratio detection,the method combined with matched filter can detect weak signals in virtue of the characteristics that High-Order Cumulant has over two-order information and good performance for suppressing Gaussian noise,which can obtain more detection probability under low SNR.Monte-Carlo simulations have shown that the proposed method is effective.
