| 摘 要： | LTE采用虚拟MIMO技术来解决终端安装多天线的问题.用户配对是VMIMO技术中一个重要而独特的环节,设计配对算法必须同时考虑系统吞吐量和用户公平性.该文在分析了传统用户配对算法的基础上,针对DPS算法不能满足低SNR用户需求的缺陷,提出了一种根据SNR情况改进的配对算法.仿真数据显示该算法能有效提高系统吞吐量,保证用户之间的公平性,有很大的优越性.

| Abstract: | Long-term evolution(LTE) adopt Virtual MIMO(VMIMO) technology to resolve some great problem when we install multiple antennas at user equipments(UEs).Pairing is an important and unique aspect in VMIMO system,it needs to take both throughout and user fairness into consideration.In this paper,after studing in traditional pairing scheduling,we propose a pairing scheduling considering user's SNR(PSCSNR) to deal with the defect of the weakness when we use DPS in low SNR user.Simulation result shows that comparin... |
