Design of A Bidirectional Multiband Radio Over Fiber for 5g New Radio

Abstract

The invasion of innovative applications in sensing, virtual reality, imaging automation and cognition demands high-level capacity and latency. The 5G new radio (NR) will serve multiple applications simultaneously. The radio-over-fiber (RoF) transmitting the millimeter-wave (mm-wave) signal is the best-suited solution for growing data traffic as well as reducing the mm-wave small cell equipment complexity. The novel multiband bidirectional RoF scheme reuses the mm-wave carrier for both uplink and downlink over a single fiber reducing the overall complexity, volume, cost, and power consumption of the system and serving multiple applications simultaneously. newlineIn this thesis, first, the fundamentals of multiband bidirectional RoF as front haul link for multiband 5G NR signals are elaborated. The key aspects of deploying a scalable and robust bidirectional 5G NR based on RoF are discussed considering the limitations. The major objectives of our research work the (i) SBS mitigation in bidirectional RoF systems; (ii) modified OSSB modulation scheme; (iii) Channel equalization by sparse VNLE and (iv) design and simulation of multiband bidirectional RoF for 5G NR application newline
