A New Feature Vector Using Selected Line Spectra for Pulsar Signal Bispectrum Characteristic Analysi
[期刊论文] 作者：Zhen-Hua Xie,Lu-Ping XU,Guang-,
来源：中国天文和天体物理学报：英文版 年份：2007
Average pulse profiles of pulsar signals are analyzed using the bispectrum tech-nique. The result shows that there are nonlinear phase couplings between the two...
,A block zero-padding method based on DCFT for L1 parameter estimations in weak signal and high dyna
