摘要
本文主要讨论自适应调制与编码系统 (AdaptiveModulationandCodingsystem)的原理 ,介绍AMCS实现的几个关键技术 ,包括RCPT(速率适配凿孔turbo)码、高阶调制、H -ARQ和MIMO(多输入多输出 )系统。介绍了在WCDMA的高速下行分组接入业务 (HSDPA)中使用的自适应调制编码机制 。
The principle of adaptive modulation and coding system (AMCS) is discussed. The key techniques in AMCS are introduced , including RCPT(Rate compatible puncture turbo) code, high order modulation, H-ARQ and MIMO( multiple input and multiple output) system. The application of AMCS in the WCDMA high speed downlink packet access is introduced, and the additional complexity of the equipment is discussed.
