I. Introduction
Technological and cultural evolution would substantially depend on wireless communication systems. In the few past years, wireless communications became ubiquitous, and were deployed for many different applications, from communications to sensing [1], [2]. Ultra high-data rates and improving performances of wireless networks are important subjects of concern to satisfy future customer requirements. Since a majority of current wireless communication systems utilizes highly crowded frequency bands, the use of higher carrier frequencies such as millimeter-wave (mm-wave) frequencies is proposed to benefit from the large amount of available bandwidth [2]. The integration of both optical and radio networks helps to mitigate the complexity of carrier generation and to avoid high transmission loss in electronic components at mm-wave frequencies. Radio-over-fiber (RoF) systems provide high-bandwidth front/backhaul services and enable scalable/manageable networks without complex interface structures and multiple overlaid protocols [3]–[5].
