The proposed 3x3 MIMO fiber-wireless system in the W-band with WDM and PDM capabilities achieved total capacities of approximately 110 Gb/s and 132 Gb/s with corresponding spectral efficiencies of approximately 8.5 and 10.2 bit/s/Hz, respectively. The system demonstrated satisfactory performance for offset quadrature amplitude modulation-based filter-bank multicarrier signals, and is applicable to WDM and combined WDM/PDM RoF transmissions. It provides a scalable solution for large-scale MIMO signal transportation and shows promise for future mobile transport and radio access networks in high-frequency bands.
We propose and demonstrate a 3 x 3 full multiple-input multiple-output (MIMO) fiber-wireless system in the W-band with wavelength-division multiplexing (WDM) and polarization-division multiplexing (PDM) radio-over-fiber (RoF) transmission capability. The system is realized using two highly stable RoF links based on the optical self-heterodyne method and PDM transmission in one of the RoF links. We experimentally demonstrate and confirm satisfactory performances for a 3 x 3 MIMO offset quadrature amplitude modulation-based filter-bank multicarrier signal. Total capacities of approximately 110 and 132 Gb/s, corresponding to spectral efficiencies of approximately 8.5 and 10.2 bits/s/Hz, respectively, are achieved for the system using antennas placed in the same and alternately different polarizations, respectively. The system is applicable to WDM and combined WDM/PDM RoF transmissions. It provides a scalable solution for facilitating large-scale MIMO signal transportation and can be a promising solution for future mobile transport and radio access networks in high-frequency bands.
