60 ghz rof system based on ir-mbook transmitter and non-coherent receiver

International audienceA new approach to implement a Radio over Fiber (RoF) system for millimeter wave (mm-wave) is proposed and investigated. At the Central Station (CS) the mm-wave signal is produced using Impulse Radio Multiband On-Off Keying (IR-MBOOK) architecture. Then, we use an external modulator to modulate the optical signal that propagates to the Base Station (BS) through the optical fiber. This system is proposed as a solution to deal with the demands of multi-Gbps data transmission in the 60 GHz band and beyond, for nomadic applications. Low complexity, cost reduction, and performance enhancement are achieved by simplifying the mm-wave generation method. The IR-MBOOK design and external modulation are jointly used in this work. The optical link is based on Single Mode Fiber (SMF) to reach a long distance. At the receiver, a non-coherent receiver has been used in order to down-convert the signal to the baseband. The system efficiency is evaluated and analyzed by quality factor (Q factor) performance. Simulation results show the efficiency of monocycle pulse compared with Gaussian pulse shape, and RoF system with transmission rate of 4 Gbps is successfully achieved up to 45 km. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2020
