This work experimentally demonstrates the efficacy of the 2 × 2 multiple-input multiple-output (MIMO) technique for capacity improvement of a 60-GHz radio-over-fiber (RoF) system employing single-carrier modulation format. We employ frequency domain equalization (FDE) to estimate the channel response, including frequency response of the 60 GHz RoF system… (More)
We experimentally investigate the wireless channel characteristics of 2x2 60-GHz MIMO OFDM RoF system with 3.5-m wireless distance. With lattice-reduction-aided detection, the achievable data rate can be improved from 0.58Gbps to 12.61Gbps for the worst case.
