The input signal consists of a weak low-frequency sinusoid T(t), an additive Gaussian white noise [xi](t), and an additional high-frequency sinusoid S(t).
A simulation signal is constructed by combining a sinusoid with an additive Gaussian white noise. The number of sampling points R is 4000, and the sampling frequency [f.sub.s] is 12 kHz.
With 20 dB additive Gaussian white noise added to the scattering data, the errors are larger, but still less than 7% (most below 5%).
With 20 dB additive Gaussian white noise added to the scattering data, the relative errors are larger, but they are still acceptable, because they are all less than 8% (most around 5%).
