[摘要] 提出了一种基于滤波器组多载波(FBMC)的多点协作(CoMP)传输技术,并搭建了基于软件无线电设备(USRP)的FBMC-CoMP通信系统原型验证平台,认为通过设计预编码可以消除小区间干扰。为验证所提出FBMC-CoMP传输技术及预编码设计的可行性,在原型验证平台上进行了FBMC-CoMP异步能力及误码率等性能的测试。测试结果显示:FBMC-CoMP能够抵抗的最大基站延时差为0.7 us,此时通信误码率小于0.003。

[Abstract] In this paper, a new coordinated multipoint (CoMP) transmission technology based on filter bank multicarrier (FBMC) is proposed, and a prototype verification platform for FMBC-CoMP communication system using the universal software ratio peripheral (USRP) is built. And the co-channel interference among cell edge users can be eliminated by the precoding design. In order to verify the FBMC-CoMP transmission technology and the precoding, a test on the asynchronous ability and the bit error rate of FBMC-CoMP is made. Experiment results show that the maximum base station delay difference which FBMC-CoMP could resist to is 0.7 us, and the bit error rate is less than 0.003.
