摘要
作为LTE-A/5G网络的关键技术,MIMO的标准演进路线一直备受关注。结合3GPP标准对MIMO的规范进行梳理,从分集技术、空间复用技术、预编码技术、波束赋形技术、多用户MIMO技术等多个层面的技术演进入手,全面剖析MIMO技术从R11-R15阶段的技术演进脉络,掌握MIMO的发展方向。
As the key technology of LTE-A/5G network,the standard evolution route of MIMO has always attracted much attention.Combining the 3GPP standards to sort out the MIMO specifications,and starting from the technological evolution of diversity technology,spatial multiplexing technology,precoding technology,beamforming technology,multi-user MIMO technology,etc.,the technological evolution of MIMO technology from R11-R15 stage is comprehensively analyzed,and the development direction of MIMO grasped.
