Seamless translation of optical fiber PolMux-OFDM into a 2×2 MIMO wireless transmission enabled by digital training-based fiber-wireless channel estimation

• We propose and demonstrate a 2 × 2 multiple-input multiple-output (MIMO) wireless over fiber transmission system. Seamless translation of two orthogonal frequency division multiplexing (OFDM) signals on dual optical polarization states into wireless MIMO transmission at 795.5 Mbit/s net data rate is enabled by using digital training-based channel estimation. A net spectral efficiency of 2.55 bit/s/Hz is achieved.
