传统室分错层单支路泄漏实现MIMO双流效果

MIMO double flow effect is realized by single branch leakage in traditional chamber split-layer

目前绝大多数楼宇的LTE室内分布系统方案是在原有的单通道分布系统基础上进行简单的合路,无法发挥LTEMIMO双流传输模式的技术优势,损失LTE室内分布系统约50%的容量。为低成本实现4G室内分布系统中的MIMO双流效果,提高4G用户感知,本文提出通过对RRU双通道接口与楼宇奇偶层进行错层连接,将原传统平层MIMO双支路改为垂直面的隔层双支路,通过上下楼层泄漏信号产生MIMO效果,达到提高用户下载速率的目标。

At present,the LTE indoor distribution system solution of most buildings is simple combination based on the original single-channel distribution system,which cannot take advantage of the technical advantages of the LTE MIMO dual-stream transmission mode and loses about 50%of the capacity of the LTE indoor distribution system.In order to achieve low-cost MIMO dual-stream effects in 4G indoor distributed systems and improve 4G user perception,this paper proposes to connect the RRU dual-channel interface to the parity layer of the building by split-layer connection to change the original traditional flat-layer MIMO dual branch to a vertical plane.The double-branch of the compartment has a MIMO effect through the leakage signals of the upper and lower floors to achieve the goal of improving user download rate.
