Abstract
To maximize file transfer from space vehicles to the Earth, we propose a new space-to-earth content transfer protocol that combines turbo codes, RaptorQ codes, real-time channel prediction, and dynamic code-rate selection. The protocol features a practical signal-to-noise ratio prediction model that facilitates periodic adjustment of the turbo encoder to achieve adaptive rate transmission. Our simulation results indicate that an increase of about 20% in file transfer rate is achievable using the proposed protocol.
