摘要
介绍了大规模MIMO(Massive MIMO)测试台研究现状,提出了一种基于NetFPGA(Net Field-Programmable Gate Array)+USRP(Universal Software Radio Peripheral)的MIMO(Multiple Input Multiple Output)传输平台构架,详细介绍了该平台各个模块组成,并通过实验验证了利用NetFPGA+USRP搭建MIMO传输平台的可行性和可靠性。该平台具有较好的开放性和可拓展性,各模块属性可快速被定义,通过扩展前级NetFPGA板卡,还可以实现更大规模的MIMO传输平台搭建。由于Net FPGA与USRP的可编程性,使实验平台还可做其他MIMO通信方面的实验,方便对MIMO物理层处理、多路高速数据交换、流量控制及通信接入算法等研究。
In this paper,the research status of Massive MIMO test bench is introduced.A MIMO（ Multiple Input Multiple Output）transmission platform architecture based on Net FPGA（ Net Field-Programmable Gate Array） ＋ USRP（ Universal Software Radio Peripheral） is proposed.The feasibility and reliability of constructing MIMO transmission platform with Net FPGA ＋ USRP are verified by experiments.The platform has better openness and extensibility,and the module attributes can be defined quickly. The expansion of the front-end Net FPGA board can also realize the construction of a Massive MIMO transmission platform.Because of the programmability of Net FPGA and USRP,the experimental platform can be used for other MIMO communication experiments. It is convenient for MIMO physical processing,multi-channel high speed data exchange,traffic control and communication access algorithm research.
