A approaches based on cross-high-order spectrum to identify the digital system
Qing Mei Jia · 2000
The modern cross high order cumulant(CHOC),such as the cross fourth order cumulant(OFOC),is used to identify the digital system and prove that the CHOC(CFOC)can control the relevant noises and gaussian noises,and based on the cross high order spectral(CHOS)Yule Walker equations,this method can efficiently distinguish the signal buried in the colored noises and have excellent robustness compare with others so that these methods are very suitable to be applied in project.
