摘要
自适应调制编码技术是克服无线信道的时变性的一种重要链路适应技术。常用的链路自适应技术有自适应功率控制、自适应调制编码、自适应帧长等。本文主要介绍了两种自适应调制编码技术 。
Adaptive modulation and coding is a key link adap ta tion technology to overcome the time variable in wireless channel The l ink adaptation technology includes adaptive transmit power control, adaptive mod ulation and coding, adaptive frame length control etc This paper introduces two adaptive modulation and coding and analysis their merits and disadvantages
