摘要
在上行链路方向,3GPPLTE采用SC-FDMA作为多址技术,该技术有助于实现较高的功率放大器效率,且对于FDD和TDD工作模式都是适用的。本文分析了SC-FDMA发射机和接收机结构与原理,描述了SC-FDMA系统的数据速率调整方法,讨论了SC-FDMA系统的资源分配过程,介绍了SC-FDMA的立方量度。
In the uplink direction 3GPP uses SC-FDMA for multiple access, which enables better power amplifier efficiency and is valid for both FDD and TDD modes of operation. This paper analyzes the structure and principle of SC-FDMA transmitter and receiver, describes the adjusting method of data rate in a SC-FDMA system. Furthermore, this paper discusses the process of resource allocation in a SC-FDMA system. In conclusion, we introduce the CM of SC-FDMA.
