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 and the MIMO wireless channel. Using FDE and MIMO techniques, we experimentally demonstrate the doubling the of wireless data capacity of a 60 GHz RoF system to 27.15 Gb/s using 16-QAM modulation format, with transmission over 25 km of standard single-mode fiber and 3 m wireless distance.
这项工作通过实验证明了2×2多输入多输出（MIMO）技术对于采用单载波调制格式的60GHz光纤无线（RoF）系统容量提升的有效性。我们采用频域均衡（FDE）来估计信道响应，包括60GHz RoF系统和MIMO无线信道的频率响应。利用FDE和MIMO技术，我们通过实验证明，采用16-QAM调制格式时，60GHz RoF系统的无线数据容量可翻倍至27.15Gb/s，传输距离为25km标准单模光纤和3m无线距离。
