TD-SCDMA R4与TD-HSDPA的干扰共存性能研究.pdf.pdf

TD-SCDMA R4与TD-HSDPA的干扰共存性能研究摘要目前, 。这两个网络间共存干扰的研究, 网络的部署和规划具有重要的意义。但是,目前相关研究开展的还非常有限。 ,在未来具有非常广阔的发展空间。如何设置家庭基站的最大发射功率,在 SA 中家庭基站研究的热点问题之一。在3GPP中已经进行了WCDMA 家庭基站的系统间干扰分析,。。依据实际网络的部署情况及3GPP的相关标准,,包括组网方式、部署场景、传播模型和干扰模型等。并通过仿真评估了不同场景下系统共存对小区性能的影响,给出了 。之后,基于家庭基站特点和其与一般TD-SCDMA系统的区别, SA中讨论达成的基本共识,本文给出了家庭基站共存干扰问题的基本研究假设,并在此基础上评估了家庭基站采用固定发射功率时对宏小区的干扰情况。最后,文章总结了目前研究的进展情况并对未来研究的发展做出了展望。 n呵TERFEI吲CE RESEARCH OFTD—SCDMA R4 AND SYSTEM ABSTRACT Ⅳ【A work are now under deployment on these two above works iSveryimportant tothedeployment ofthem.
