Composeable Chat over Low-Bandwidth Intermittent Communication Links

摘要

Intermittent low-bandwidth communication environments, such as those encountered in U.S. Navy tactical radio and satellite links, have special requirements that do not pertain to commercial applications. They need a bandwidth-compression algorithm that limits the dependence of encoding symbols on previous state information because the loss of the previous state has a ripple effect on the interpretation of what follows. They also need a homing mechanism to permit synchronization at an arbitrary point in the broadcast message stream when reception is re-established, ideally, without negotiation between the transmitter and the receiver.
