Distributed MIMO Antenna Architecture for Wireless-over-Fiber Backhaul with Multicarrier Optical Phase Modulation
Coherent communications Phase modulation Radio frequency photonics
2015/5/26
A novel optical phase-modulated wireless-over-fiber backhaul architecture for next generation cellular network is presented and experimentally demonstrated for high capacity wireless multicarrier upli...
MIMO System Capacity Improvements Using Radio-over- Fibre Distributed Antenna System Technology
Fiber optics communications Radio frequency photonics Fiber optics links subsystems
2015/5/25
The effect of antenna separation in a 3×3 MIMO system using RoF DAS technology is investigated. Larger antenna separation is found to improve the throughput due to reduced channel correlation and impr...
