Loran-C cycle identification and ECD estimation in presence of white Gaussian noise

A Loran-C system is a hyperbolic navigation system which works based on the TOA methods. The cycle identification and ECD estimation accuracies have considerable effects on the Loran-C system receivers localization accuracy so it is important to estimate the reference point and ECD as precisely as possible. White Gaussian noise degrades the performance of cycle identification and ECD estimation. Also, the error in cycle identification or ECD estimation degrades the performance of another one. In this paper two proposed methods for cycle identification and ECD estimation are evaluated in presence of white Gaussian noise and it will be described the relations between the cycle identification and ECD estimation. The simulations results show that the proposed methods are robust in presence of white Gaussian noise.
