A Fast Carrier Synchronization Method for Earth-Space Communication Systems

Abstract

AbstractThis paper presents a fast carrier synchronization method for earth-space communication systems in which pseudnoise (PN) sequence is adopted to help carrier synchronization. The method utilizes PN parallel correlation since it can provide a wide acquisition range while reducing the acquisition time. Moreover, a fine PN tracking is introduced to ensure the robustness of the proposed method. Simulations in MATLAB show that the proposed method can provide wide acquisition range, short acquisition time and small tracking jitter in both distorted static and dynamic channels
