摘　　要：移动互联网发展对移动无线网络性能和数据速率提出更高要求,自适应调制与编码AMC因其在提高频谱效率方面效果显著,成为LTE系统的一项关键技术。本文提出了LTE系统中下行AMC系统模型,并详细阐述了一种LTE下行链路的AMC算法及实现步骤、方法,最后对该方案在实际部署应用中的适用性进行了讨论。The development of mobile internet puts forward higher requirements for the performance and data rate of mobile wireless networks. Adaptive modulation and coding AMC has become a key technology in LTE system because of its remarkable effect on improving the spectrum efficiency. In this paper,a downlink AMC system model in LTE system is proposed,and a AMC algorithm for LTE downlink and its implementation steps and methods are described in detail. Finally,the applicability of the scheme in practical deployment is discussed.
