Code-Division Space-Time Fountain Code for Plasma Sheath Communication

Abstract

Influenced by the special physical characteristics of the plasma sheath and the parameters of the aircraft’s attitude, the channel containing the plasma sheath can be regarded as a special kind of discontinuous channel. A code-division space-time fountain code form is proposed that is suitable for the spatial characteristics of the plasma sheath channel. Simulation results show that the use of code-division space-time fountain code maximizes the use of the airspace resources in the plasma sheath channel. The scheme proposed in this paper can be used to alleviate the “ionization blackout” problem faced by hypersonic vehicles in the reentry process.
