无线信道是十分复杂的传输信道,具有时变特性和衰落特性,AMC(自适应调制和编码)技术因具有能够使通信系统与无线信道相适应的特性,而成为了3 GPP(第三代合作伙伴计划)LTE (长期演进)系统的一项关键技术。文章针对 LTE系统提出了一种 AMC实现方案,并对该方案的性能进行了仿真测试。仿真结果表明,该 AMC方案能够有效地提高系统吞吐量。

Wireless channels are complicated with time-variant and fading characteristics.As the Adaptive Modulation and Cod-ing (AMC)technology can make communication systems adaptive to these channels,it has become a key technology to the 3GPP Long Term Evolution (LTE)system.This paper presents an AMC implementation scheme for the LTE system and simulates and tests its performances.The simulation results indicate that this scheme effectively improves the system through-put.
