摘要
提出了一种同时考虑光链路和LTE/LTE- a信号质量的基于RoF的移动前传链路设计方案。提出了支持LTE/LTE- a业务的模拟链路中CNR的要求，并研究了模拟链路质量对LTE/LTE- a信号的影响。给出了在20 km SMF链路上传输不同中频数的LTE-A信号后的EVM测量。
Design of RoF based mobile fronthaul link with multi-IF carrier for LTE/LTE-A signal transmission
We report a design of RoF based mobile fronthaul link considering quality of optical link and LTE/LTE-A signal simultaneously. The requirement of CNR in analog link supporting LTE/LTE-A services is presented, and effects of analog link quality on LTE/LTE-A signal is investigated. The EVM measurement after transmission of LTE-A signal with various numbers of intermediate frequency over 20 km SMF link is also presented.
