摘要

Some methods for identification of the useful information about a process are based on the autocorrelation function and power spectrum of the signals. These methods can't be applied for detecting and characterizing the type of nonlinearity in a system from its output signal. Quadratic phase coupling is a particular case of nonlinear process that may occurs when a signal is passed through a square-law (nonlinear) system. Higher-order statistics are very important tool in this problem because quadratic phase coupling can be detected from the bispectrum of the signal.
