Abstract

5G is emerging, but the current fronthaul transmission technologies used for 3G and 4G may not be efficient and appropriate for 5G. It has been found that frequency division multiple access (FDMA) and time-division multiple access (TDMA) based radio over fiber (RoF) may be considered the most appropriate for 5G fronthaul transmission technology. Due to analog RoF transmission, broadband linearization is required. In this work, both electrical and optical broadband linearization techniques are reviewed.

Xiupu Zhang (M’00–SM’07) received B.Sc. degree from the Harbin Institute of Electrical Technology (now Harbin University of Science and Technology), Harbin, China, in 1983, M.Sc. degree from the Beijing University of Posts and Telecommunications, Beijing, China, in 1988, and Ph.D. degree from the Technical University of Denmark, Lyngby, Denmark, in 1996, all in electrical engineering.

From 1983 to 1985, he worked for manufacturing fibers and fiber cables in China. From 1985 to 1988, he studied for the Master’s degree at Beijing University of Posts and Telecommunications, China. From 1988 to 1992, he was engaged in the construction of telecommunication networks in Beijing, China. From 1992 to 1996, he studied for the Ph.D. degree at the Technical University of Denmark. He then spent approximately one and a half years at Chalmers University of Technology, Göteborg, Sweden, where he investigated high-speed fiber-optic transmission. From 1998 to 2002, he worked, as a senior engineer, in the fiber-optics industry, involved in design of repeaterless fiber-optic transmission systems, design of erbium-doped fiber amplifiers and fiber Raman amplifiers, design of optical transmitters and receivers, and design of metropolitan optical networks, in North America including Montreal and Ottawa, Canada, and Piscataway, NJ, USA. In June 2002, he joined Concordia University, Montreal, Quebec, Canada and became an associate professor. Currently, he is a full professor in the Department of Electrical and Computer Engineering, Concordia University. He has authored and co-authored about 200 refereed technical publications, including ~110 journal publications published in IEEE, Optical Society of America, and other related journals, and ~100 conference presentations in IEEE related conferences such as the Optical Fiber Communications Conference.
