Abstract

The attainable Frame Error Rate (FER) in satellite burst communication is much too high when a classical Costas Loop is used as the carrier synchronizer. This high FER is due to cycle slips and hang-up of the Costas Loop. We demonstrate the potential to achieve a FER of 3×10-6 using 3 parallel Kalman tracking loops with their initial frequencies spaced apart. We also propose an algorithm for selecting the correct loop for demodulation and use data aided and optimal phase detection for the preamble and payload respectively. This dramatic improvement is at a reasonable complexity.
