Abstract:The development of mobile internet puts forward higher requirements for the performance and data rate of mobilewireless 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.
