Abstract :
Two extended-range phase detectors (PDs), including the tanlock PD, are derived from the iterated extended Kalman filter. Fast converging recursion and concise initialization equations are given. Simulations of a Wiener phase process and a first-order Markov FM process show slightly reduced mean-square error near threshold and faster phase acquisition than a sinusoidal PD
