摘要：
We propose and experimentally demonstrate a radio-over-fiber (RoF) system employing subcarrier-index modulation (SIM) orthogonal-frequency-division multiplexing (OFDM) signal. Thanks to the introduction of a new freedom in terms of SIM, a robust and energy-effective transmission solution is achieved for the RoF system. In the experiments, the 8-GHz QPSK-SIM-OFDM and conventional QPSK-OFDM signals are transmitted in an RoF system with a 10-km single-mode fiber (SMF) link. Compared with conventional QPSK-OFDM, the proposed QPSK-SIM-OFDM for RoF system is verified with higher energy efficiency and a lower bit error ratio (BER) for a medium or high signal-to-noise ratio (SNR). Concerning the energy efficiency of the proposed ROF system, defined as the total amount of reliably decoded bits normalized by the energy, it is about 1.5 times higher than that of conventional QPSK-OFDM.
