The cross-high-order-cumulant such as the cross-fourth-order cumulant is firstly proposed to measure the signal and for the first time prove that the CHOC can control the non-relevant noises and Gaussian noises. And based on the cross-high-order spectral Yule-Walker equations, the sinusoidal signal matrix is decomposed by the way of singular value decomposition method.

Based on the proposed genetic design, the maize inbreed lines JB and Y53, which are the parental lines of maize hybrid suyu 16 with strong heterosis, were used to create the mixed mapping population with two different cytoplasm backgrounds. The proposed method for mapping cytonuclear epistatic QTL were used to identify the cytonuclear QTL underlying maize agricultural and yield traits.

Secondly, according to the spectral correlation theory of second order cyclostationary processes, maximumlikelihood filters are used to estimate the cyclic spectra. By estimating the crossspectra of the two frequency shifted versions of cyclostationary signal, the cyclic spectra can be obtained. The analysis effective bandwidth of maximumlikelihood filters is studied in details. In case of cross-spectra estimation, the analysis effective bandwidth of maximum-likelihood filters is not correct. A new method to calculate the analysis effective bandwidth is presented.
