摘要
为了提高LTE无线空口容量,对下行256QAM和上行64QAM高阶调制技术及其性能进行了分析,并结合实验室测试结果和LTE现网的无线信号覆盖质量,评估高阶调制技术在实际网络中的性能增益。研究结果表明,高阶调制在室内场景下具有较为明显的增益。
In order to improve the capacity of the air interthce for LTE, downlink 256QAM and uplink 64QAM high-order modulation techniques and their performance were analyzed. The performance gain of high-order modulation techniques in actual networks was evaluated according to the tested results in laboratory and wireless signal coverage quality in existing LTE networks. Research results demonstrate that high-order modulation has a significant gain in indoor scenario.
