Abstract: Fast parameter estimation of sinusoidal frequency modulation signal (SFM) in additive white Gaussian noise is considered. A technique based on Carson's rule is developed to estimate the frequency modulation index; the carrier frequency is calculated using the symmetrical property of side-frequency components; the instantaneous frequency is computed to get the modulation frequency. The Cram¨¦r-Rao lower bound (CRLB) of parameter estimation of SFM is also been derived. Monte Carlo simulations show that the parameter estimation accuracy is acceptable when the SNR is above 6dB.
