中文摘要：
围绕正交频分复用-无源光网络（OFDM-PON）系统中非线性损伤的补偿问题开展研究.使用VOLTERRA模型对非线性补偿器进行辨识,利用差异因子并结合QR分解,推导出修正向量的解析表达式,提出模型核向量的自适应修正方法,形成正交频分复用-无源光网络系统中非线性损伤的补偿算法.仿真结果表明,所提出的方法可使系统误比特率提升1％～3％,在系统比特率为130 Gb/s时,系统误比特率可保持在1％左右.
英文摘要：
The Nonlinear disturbance issues were considered for orthogonal frequency division multiplexing-passive optical networks （ OFDM-PON ） systems. A model with VOLTERRA series was used for identifying the nonlinear compensator. By using the difference factor and QR decomposition, adaptive method for the kernel vector was deduced. As a result, the nonlinear compensation algorithm for OFDM-PON systems was proposed. Simulation results show that the proposed scheme can improve the system BER performance by 1-3%, and when the system bit rate is 130 Gb/s, the system BER can maintain at about 1%.
