Frequency rate estimation based on fourth order sample moments

• Estimation of the frequency rate of linear frequency modulated signals based on phase angles of fourth order sample moments is considered. Three low-complexity estimators are proposed whose performance is close to optimal, that is their error variance is close to the Cramer-Rao lower bound
