高阶调制技术在LTE网络中的研究及应用
摘要
为了进一步提升LTE网络无线空口容量
对LTE-A中的高阶调制技术进行研究及应用验证。理论上
上行16 QAM到64 QAM可提升50%的速率
下行64 QAM到256 QAM可提升33%的速率。本文通过实测对比验证了高阶调制的效果
而且无线环境越好
速率增益效果越明显。
Abstract
In order to further improve the capacity of wireless air port in LTE network
the high-order modulation technology in LTE-A is studied and verified. Theoretically
uplink 16 QAM to 64 QAM can increase the rate by 50%
downlink 64 QAM to 256 QAM can increase the rate by 33%. In this paper
the effect of high-order modulation is verified by the comparison of the measurement results. The better the wireless environment is
