Abstract

The Costas loop is a special type of Phase locked loop widely used in wireless communication systems. HF band always plays an important role in wireless communication systems with several applications in many areas. In this paper, the modified Costas loop for frequency tracking in HF communication system is proposed. The improved performance in phase and frequency tracking is very important for Automatic Link Establishment (ALE) mechanism in HF communication system in order to ensure the quality of wireless channels. The simulation results using Matlab for Frequency estimation of HF signals with the proposed architecture will be shown and analyzed to verify its performance.
