Abstract
ROF is the technology that integrates optical communication and wireless communication. It not only possesses the characteristics of high speed and long distance in optical communication, but also has the characteristics of flexible in wireless communication. GFDM is one of 5G's alternative technologies for high-frequency millimeter waves. This paper proposes and verifies that in the GFDM-ROF system with MIMO, cascaded Turbo-STBC coding can improve the reliability of the entire system. We use Turbo code as the out-of-channel code, and STBC code as the intra-channel code. When using two transmitting antennas and four receiving antennas and the SNR is higher than 5 dB, the BER is below 10-6. Furthermore, based on this system, under high load communication conditions, we proposed an adaptive coding technology with excellent performance and it can reduce system load rapidly.
