摘要
为提高光纤多载波滤波器组(FBMC-OQAM)系统的色散补偿控制性能,提出一种基于子载波多抽头分数间隔并联多级均衡器的光纤色散补偿控制算法。首先,针对考虑只有一个极化的FBMC-OQAM传输问题,利用傅立叶变换建立系统色散补偿控制问题模型;其次,为提高补偿控制过程的有效性,建立了多抽头分数间隔子载波均衡器,并在此基础上建立了并联多级均衡器,消除由信道变化和符号估计造成的k阶失真,实现了模型均衡补偿控制性能的提升;最后,通过仿真实验显示所提算法具有相对更小的解调误差,从而验证了所提方法的有效性。
In order to improve the dispersion compensation performance of the optical fiber multicarrier filter bank(FBMC-OQAM) system, a fiber dispersion compensation algorithm based on sub carrier multi tap and fractionally spaced parallel multistage equalizer is proposed. Firstly, in view of the FBMC-OQAM transmission problem with only one polarization, the Fourier transformation is used to establish the system dispersion compensation model. Secondly, in order to improve the effectiveness of the compensation process, a multi tap fractionally spaced equalizer sub carrier is established, and based on the parallel multi order k equalizer, distortion caused by the estimation is eliminated by the channel change and symbols, which improves the performance of the model balanced compensation; Finally, the simulation experiment shows that the proposed algorithm has a relatively small demodulation error, thus verifying the effectiveness of the proposed method.
