Improved algorithm for integrated trispectrum
Zongchuang Liang, Xingzhao Liu, Yongtan Liu · Electronics Letters · 2000
A method for reducing the estimation variance of an integrated trispectrum under low signal-to-noise ratio (SNR) and short data sample conditions is presented. An analysis of the results of a simulation using this method, and a comparison with the power spectrum method and integrated trispectrum method, are presented.
