5G NR MIMO Enabled MultiBand Fiber Wireless System using Analog Optical Front Haul

Abstract

This paper presents an unprecedented realization of fiber based analog radio over fiber (A-RoF) along 2×2 multi input multi output (MIMO) wireless system as a realistic front haul scenario using fifth generation (5G) new radio (NR) multiband signals. The proposed 5G NR signals comprise of 5 GHz waveform and 20 GHz-200 MHz bandwidth. The A-RoF 10 km of Standard Single Mode Fiber. The EVM performance for the system meets the 3GPP Release 16. Furthermore, EVM performance for received optical power is evaluated up to 200 MHz bandwidth. It can be concluded that A-RoF-MIMO integrated system suits the required range of the 5G C-RAN fronthaul networks and can be a propitious candidate for future mobile haul applications.
