Abstract

Plasma sheath can interfere with normal communication between aircraft and ground control station, and the large transmission delay and high information error rate it introduces make traditional feedback retransmission transmission systems ineffective. The use of forward error correction codes such as fountain codes can effectively solve the problem of unidirectional transmission. However, the harsh transmission environment of the plasma sheath channel can cause errors in some information bits of the fountain code encoding packets. Traditional hard decision decoding methods will discard these encoding packets, which greatly wastes valuable channel resources. This article proposes a fountain code soft decoding method suitable for plasma sheath channels, aiming to fully use the available information in the encoding packets. The simulation results show that this method can improve the transmission efficiency of the entire plasma sheath channel.
