Title
Quality-based channel selection in multi-channel radio-over-fiber system
Abstract
Radio over Fiber (RoF) is a promising solution for wireless access services by transferring the heterogeneous radio signal via the optical fiber link. However, RoF devices have nonlinear characteristics which create intermodulation products in system. The intermodulation distortion (IMD) interferes uplink RF signals in the presence of coupling between downlink and uplink antennas in the base station (BS). This paper proposed the performance evaluation due to coupled downlink interfere to uplink antenna. The carrier to distortion plus noise ratio (CDNR) is evaluated for all combinations. By using NS3 network simulator, the result shows the best combination achieves better performance. Which coupled downlink interfere in uplink signal can be reduced when amount of downlink packet is decreased.
