A New Design Method For Unbiased Finite Memory Digital Phase-Locked Loop
Abstract
In this paper, we presented the design method for the unbiased finite memory digital phase-locked loop
(UFMDPLL). We analyzed the characteristic of relation between horizon size and noise covariances of the UFMDPLL by
introducing the horizon equation. The horizon equation, which is a function of horizon size N and noise covariances, is derived
from error variance and ensuring unbiasedness property. Through simulations, we present the effects of among the noise
covariances on the optimal horizon size of UFMDPLL.
