论文摘要
预编码已成为一种有希望的多用户传输技术,可以满足卫星通信系统的新兴吞吐量需求,同时等待技术成熟度以利用更高的乐队。预编码可以通过空间处理来减少共通道梁之间的干扰,同时促进攻击性频率再利用和提高光谱效率。卫星系统提供多种系统和服务配置,从而产生不同的预编码器设计方法。本文探讨了引入预编码的动机,在各种情况下为他们的理论发展提供了深入的见解,并为未来的发展提供了一些途径。
Precoding has stood out as a promising multi-user transmission technique to meet the emerging throughput demand of satellite communication systems while awaiting the technological maturity for exploiting higher bands. Precoding enables the reduction of interference among co-channel beams through spatial processing while promoting aggressive frequency reuse and improving spectral efficiency. Satellite systems offer multitude of system and service configurations, resulting in different precoder design methodologies. This article explores the motivation for the introduction of precoding, offers an insight to their theoretical development in a diverse scenarios and presents some avenues for future development.
