Summary: | 碩士 === 國立交通大學 === 顯示科技研究所 === 100 === The rapid growth of data rates of new wireless applications led by interactive multimedia services is driving the need for multi-Gbps wireless communication technologies in the near future. However, the bandwidth of the license free spectrum at 60 GHz is limit to 7 GHz and 60-GHz millimeter-waves have very high propagation losses rendering them more suitable for short-range wireless links (~10m). Therefore, 60-GHz radio-over-fiber (RoF) system with spatial-multiplexing MIMO technology is a promising candidate to provide broadband service, wide coverage, and mobility.
In this these, 2 x 2 MIMO technique is realized by frequency domain equalizer (FDE) to improve spectrum efficiency doubling the data throughput. We experimentally demonstrate 2 x 13.575 Gb/s 16-QAM MIMO single carrier signal transmission within 7-GHz license-free bandwidth at 60-GHz band. The power penalty is negligible after transmission over 25-km single mode fiber and 3m wireless distance.
