Synchronization Algorithm for a Satellite Communication Signals Demodulator in High Carrier Shift Conditions

摘要

This paper discusses radio interfaces in satellite communications with phase types of modulation and framed signal structure. It outlines several different frequency-time synchronization algorithms of demodulator, specifies the features and conditions for their use. As a result it describes combined synchronization algorithm, which is able to work effectively in conditions of high and variable carrier frequency shift values.
