| Abstract: | Synchronization technology is the key technology of Inmarsat satellite communication system.The initial synchronization of the downlink is an important step in establishing a link between the MES and the satellite system.In order to achieve fast and stable MES access to the network,a method for initial downlink synchronization is proposed.This synchronization method has been implemented on MES and has been applied commercially.The application results indicate that the method is stable and reliable,and the terminal can quickly register and enter the network,which can provide a reference for the design and research of satellite system terminals independently developed in China. |
