Fiber Link Health Detection and Self-Healing Algorithm for Two-Ring-Based RoF Transport Systems
Sensors, 2019 A two-ring-based radio over fiber (RoF) transport system with a two-step fiber link failure detection and self-healing algorithm is proposed to ensure quality of service (QoS) by automatically monitoring the health of each fiber link in the transport ...

Guangtongxin yanjiu, 2010 文章在建立正交频分复用（OFDM）-光纤无线电（ROF）模型的基础上,获得了在外部强度调制下无寄生动态范围（SFDR）等性能指标的表达式,着重分析了射频信号平均功率对OFDM-ROF系统的影响,并与单载波ROF系统进行了比较。结果表明,系统设计时应尽量降低射频信号平均功率以获得更好的性能指标。在相同的射频信号功率下,较单载波ROF系统而言,OFDM-ROF系统的SFDR有5 dB左右的下降,系统设计时应采取措施降低OFDM-ROF系统的峰均功率比（PA-PR）。
