中文摘要: 针对异构网络中多种网络形式互干扰问题,提出将协作多点传输技术应用于异构网络进行干扰消除。在用户终端配置多根天线的条件下,联合考虑基站间协作传输时延和信道量化误差对干扰消除的影响,利用数学理论推导这两种非理想因素导致的系统吞吐量损失,得出吞吐量损失的理论上界。仿真结果表明采用协作多点传输技术能够减小吞吐量损失,对实际系统具有指导意义。
中文关键词: 异构网  协作多点  传输时延  量化误差
Abstract:Abstract: In order to solve the mutual interference problem in heterogeneous networks, coordinated multi-point (CoMP) transmission technology was proposed to interference elimination for heterogeneous networks. When the end users configure multiple antennas, the coordinated transmission delay and channel quantization errors were considered jointly how to affect the interference elimination. By mathematical theory, the system throughput loss caused by the negative factors was analyzed, and the theoretical throughput loss upper bound was obtained. The simulation results showed that the throughput loss can be decrease by CoMP technology, which was meaningful for the actual system.
