摘要

针对ROF的非线性畸变问题，通过理论推导和ROF链路特性分析了评价ROF线性度的常用参数和ROF链路中常用的非线性畸变分量。提出了一种结合自适应补偿算法的推挽结构。仿真验证了该方法的有效性。对于测试的双音信号，仿真结果表明，该方法可以同时消除IMD2、HD2、IMD3和XMD失真分量。

Research on high-bandwidth ROF optical transceiver module based on adaptive push-pull structure

Aiming at the nonlinear distortion problem of ROF, the common parameters for evaluating ROF linearity and the nonlinear distortion components commonly used in ROF links are analyzed by theoretical derivation and ROF link characteristics. A push-pull structure combined with adaptive compensation algorithm is proposed. The method was verified by simulation. For the tested two-tone signal, the simulation results show that the method can eliminate the IMD2, HD2, IMD3 and XMD distortion components at the same time.
