Real-time gigabit RS-coded OFDM signal transmission over WDM-based X-band 2×2 MIMO RoF system

We experimentally demonstrate a real-time 2.3-Gb/s WDM-based 2×2 MIMO RS-coded OFDM-RoF system at X-band for future high-speed fiber-wireless access. The real-time measured BER after 2.24-km SMF-28 and 10-m wireless transmission is below 1× 10⁻⁹.
