摘要

本文提出了两种基于光纤数字无线电(DRoF)的集中式无线接入网架构(C-RAN)技术，分别是子载波复用(SCM)和波分复用(WDM)技术。通过评估数字化过程对系统性能、复杂性和成本的影响，进行了仿真分析。结果表明，SCM-DRoF在20km以内的光纤链路具有良好的误码率性能，WDM-DRoF在40km以内的光纤链路具有良好的误码率性能。然而，与SCM-DRoF相比，WDM-DRoF使用了更多的组件，并且产生了更高的成本。考虑到这些方面，这两种设置都可以应用于C-RAN架构。

Digital radio over fiber transmission based on SCM and WDM system for C-RAN architecture

This work presents two technologies for Centralized Radio Access Network Architecture (C-RAN) based on Digital Radio over Fiber (DRoF) respectively SCM (Subcarrier Multiplexing) and WDM (Wavelength Division Multiplexing). The simulation analysis is discussed by evaluating the impact of the digitized process on the system performance, complexity and cost. Results indicates that SCM-DRoF has a acceptable BER performance for fiber links up to 20 km and WDM-DRoF can reach up to 40 km. However, WDM-DRoF uses a greater number of components compared to SCM-DRoF and it can generates a higher cost as well. Both setup can be used applied to C-RAN architecture considering this aspects.
