基于TD-SCDMA的AMC技术研究

Research on AMC Technology Based on TD-SCDMA

自适应调制编码(AMC)是高速下行分组接入(HSDPA)的关键技术之一,它可以根据信道质量情况的改变调整调制与编码方式,从而合理地利用和分配系统资源。文中概述了AMC技术原理、特点、结构和流程,对基于TD-SCDMA的AMC技术性能进行仿真和分析。通过仿真结果,分析了在不同情况下该编码的主要技术特点,并做出了相关的结论。

Adaptive Modulation and Coding (AMC) is one of the key technologies for High Speed Downlink Packet Access (HSDPA),and it can change the style of modulation and coding according to channel quality, thus reasonably using and allocating system resources. This paper summarizes the principle, features, structure and processes of AMC technology,simulates and analyzes the performance of AMC technology based on TD-SCDMA, including the features of AMC Under different circumstances, and draws relevant conclusions.
