子载波索引功率调制(SIPM)能够利用子载波索引信息调整所对应的功率信息，它应用于光纤-可见光融合系统中，可以更好地提高该系统的传输容量。提出了一种基于子载波索引功率调制-正交频分复用(SIPM-OFDM)的全双工光纤-可见光混合系统，利用波长重用方法简化了系统的结构，并建立了SIPM-OFDM信号的产生模型，通过仿真实验验证了系统的可行性。仿真结果表明: 经过35 km标准单模光纤(SSMF)及5 m可见光双向传输之后，系统功率代价分别小于1 dB和2 dB，星座图依然清晰。

Subcarrier index power modulation (SIPM) can use the subcarrier index information to adjust the corresponding power information. It is used in a fiber-visible light fusion system, which can better increase the transmission capacity of the system. A full-duplex fiber-visible hybrid system based on subcarrier index power modulation-orthogonal frequency division multiplexing (SIPM-OFDM) is proposed. The structure of the system is simplified by using the wavelength reuse method, and the SIPM-OFDM signal is established. The model is generated and the feasibility of the system is verified by simulation verification. Simulation results show that after 35 km standard single-mode fiber (SSMF) and 5 m visible light bidirectional transmission, the system power cost is less than 1 dB and 2 dB, respectively, and the constellation diagram is still clear.
