Abstract

The channel for a Comm-on-the-move (COTM) terminal in a blockage environment communicating over a satellite can be characterized as a packet erasure channel with long channel memory and long feedback delay. The goal of our research is to enable real-time application, such as a two-way voice call, over such a challenging channel. These packets need to be delivered reliably with strict order requirement. While various automatic repeat request (ARQ) techniques are often used for this purpose, they become ineffective when the channel is severely blocked with long memory and long feedback delay, and the user desires delay performance that is only a small amount above the physical limit of the channel while not consuming too much bandwidth.
