室分错层覆盖实现MIMO双流研究与实验
摘 要 针对室分场景改造代价较高且实施困难的问题，结合学校、医院、商场、酒店等建筑的建筑结构规则一致、上下层点位一致、开阔无遮挡的特点，本文主要介绍MIMO(Multiple-Input Multiple-Output,多输入多输出)的原理，分析室分错层对实现MIMO性能的影响以及研究如何提高MIMO的性能发挥，采用错层MIMO的方法来实现双流提速，通过创新性室分RRU(Radio Remote Unit,无线远程模块)多端口错层覆盖技术手段，根据方案实施前后SINR、RSRP(Reference Signal Received Power, 参考信号接收电平)等数据的对比，以及同其他方案的比较，表明该方案基本实现双路室分的感知效果，且极大程度提升了用户感知，不但减少了投资成本与人力的消耗，且具有收益高，实施方便，适合推广等优点。

Research and experiment of MIMO dual-flow with staggered chamber coverage
Abstract Aiming at the problem of high cost and difficult implementation of room division scene reconstruction, this paper mainly introduces the principle of MIMO (Multiple-Input Multiple-Output), analyses the influence of room division on the performance of MIMO, and studies how to improve the performance of MIMO. The performance of IMO is brought into full play by using staggered MIMO method to achieve double-flow speed-up. By means of innovative multi-port staggered coverage technology of Radio Remote Unit (RRU), the comparison of SINR and RSRP (Reference Signal Received Power) data before and after the implementation of the scheme and the comparison with other schemes show that the scheme basically realizes double-channel. The perception effect of the compartment greatly improves the user perception, which not only reduces the cost of investment and human resources consumption, but also has the advantages of high income, easy implementation and suitable for promotion.
