摘要

EDGE使GSM网络能够提供第三代服务，作为UMTS核心网的一部分。这可以通过两个步骤实现:引入8PSK调制和规范从GERAN (GSM/EDGE无线接入网)到UMTS核心网的接口。本文通过使用更复杂的自适应调制方案和使用更新的编码方案(见Nanda, S. et al.， IEEE common)，进一步研究了EDGE频谱效率和容量的改进。杂志，p.54-64, 2000;Ikeda, T.等，IEEE译。Vehic。技术，第49卷，第404-12页，2000)。可以使用中断分析的理论预测来预测由于使用高阶调制而导致的性能增益。

Evolution of EDGE to higher data rates using QAM

EDGE has enabled GSM networks to offer third generation services as part of the UMTS core network. This has been possible through two steps: the introduction of 8PSK modulation and the specification of interfaces from the GERAN (GSM/EDGE radio access network) to the UMTS core network. This paper studies further improvements to spectral efficiency and capacity for EDGE through the use of more sophisticated adaptive modulation schemes, and the use of newer coding schemes (see Nanda, S. et al., IEEE Commun. Mag., p.54-64, 2000; Ikeda, T. et al., IEEE Trans. Vehic. Tech., vol.49, p.404-12, 2000). It is possible to use theoretical predictions of outage analysis to predict the gain in performance due to the use of higher order modulations.
