Abstract :
A two-channel, quadratic, nonlinear process driven by sinusoidal signals is considered. Equations for estimating the parameters of the process are derived from colored Gaussian noise contaminated observations of the process. The derivation is based on the bispectrum and cross-power spectrum of the two channels. The resulting equations are nonlinear and iterative techniques are needed to solve for the parameters
