摘要
在光通信系统中,光纤对系统性能影响较大。为了减小多模光纤的色散对光正交频分复用(OOFDM)系统性能的影响,阐述了一种新的基于恒定吞吐量的自适应调制算法,改进的算法与原始的恒定吞吐量的自适应调制算法相比,在系统误码率变化不大的情况下,算法的复杂度降低了,仿真结果证明改进算法是正确可行的。
In optical communication systems,optical fibers have strong impacts on system properties.In order to minimize the effects of dispersion of multimode fibers on OOFDM system characteristics,a novel constant-throughput-based adaptive modulation algorithm is introduced.Compared with the original one,the improved algorithm is less complicated when the system BER remain not much changed.The simulation results indicate that the improved algorithm is corrects and feasible.
