Dynamic Behavior Analysis of the Costas Loop under CW Interference Using Runge-Kutta and Galerkin Methods

Abstract: When a Costas loop is subjected to Continuous Wave (CW) interference, it will exhibit complex dynamic behavior. Because of the amplitude and frequency of the CW interference, the loop may ...
