卫星通信中的信道编码与调制技术

摘要

本文首先研究了卫星通信中的信道编码与调制技术，并对广泛应用于卫星通信的DV B-S系列标准中的信道编码与调制技术进行了对比分析，最后提出了卫星通信采用更高级信道编码和调制技术的必然性。%This paper studies the channel coding and modulation technology for satellite communication firstly.Then the comparative analyses of channel coding and modulation technology in DVB-S Series standard which is widely used in satellite communications are made. Finally the inevitability of using more advanced channel coding and modulation technology in satellite communication is indicated.
