Synchronization techniques for mobile user satellite systems
Abstract
It is shown in this paper how the structures of a class of closed loop ranging and synchronization systems follow readily from a basic open loop time dissemination and ranging technique. The channel delay is tracked in a closed loop fashion and this estimate is used to precorrect the data transmission. This dynamic precorrection reduces the influence of channel dynamics and makes the system attractive for satellite systems with mobile users.
