RoFSO technology can easily transmit radio frequency signals using optical carriers in the atmosphere. On the other hand, MIMO transmission have widely used in recent mobile communication, and there are some reports about FSOMIMO transmission. This paper demonstrates a RoFSO- MIMO transmission system which combines technologies of FSO-MIMO and RoF to enhance the flexibility of mobile front-haul. The proposed system uses pilot RF signals to estimate the FSO channel which is affected by atmospheric turbulence and so on. In this paper, we theoretically analyze RF signal quality for various turbulence conditions and show some experimental results of 2x2 RoFSO-MIMO transmission. Performance comparison results will show the effectiveness of the proposed technology. |
