Performance Analysis of Radio-over-Fiber Based on Phase-Modulation and Direct-Detection for the Future 5G Network

Access transport network plays a vital role in actual mobile networks to support the need of high data rates, real time services and spectrum efficiency. The future 5G requires an access network with high performances especially in the mm-wave bands. In this work, we propose a radio-over-fiber architecture based on intensity modulation for the downlink and phase modulation for the uplink. This solution permits to cancel optical sources and reduces electrical consumption in the multiple base stations. We focus our study on the phase modulation and direct detection link by evaluation of the quality of the wireless transmitted signal.
