Abstract-High-Order Cumulants (HOC) and cross-correlation w as combined to suppress the Gaussian color noises and the un-related noises in real applications. The cross-HOC TOA estimation model was developed based o n the diagonal slice of the forth-cross-cumulant. The eigen analysis was c arried out, and the eigen noise space and the eigen signal space was achieved. T hen the Frequency Domain TOA estimation algorithm based on Cross-HOC was developed. Different simulation experiments were carried out to draw out the conclusions.
