Proposal and analysis of novel fiber-optic relaying schemes for MIMO mobile communication

In this paper, we propose two novel fiber-optic relaying schemes, one using SM technology and another using STBC and MRC diversity reception technologies, for MIMO mobile transmission. Using single RoF link to relay MIMO signals, the proposed schemes have much lower system complexity and cost than the conventional RoF relaying system. Computer simulation confirmed that the proposed SM-RoF scheme has almost the same transmission performance, while the proposed STBC-MRC-RoF scheme can achieve much better performance compared with the conventional one.
