A New Synchronization Technique for Switched TDMA Satellite Systems

A coarse search synchronization technique is described for switched time division multiple access (TDMA) satellite systems, using a coded search signal. It is shown that this method achieves coarse search synchronization much faster, on the average, than the burst synchronization method described by Rapuano and Shimasaki. A description of an integrated synchronization system that combines the coded search signal used for coarse synchronization with the sync burst signal used for fine adjustment and tracking is included.
