分数阶正交频分复用（FrOFDM）在复用轴上具有很大的灵活性，是介于OFDM和奈奎斯特光时分复用之间的一种中间特性。在长距离传输中，FrOFDM副载波对非线性失真的影响尚未得到实验验证艾德。在这项工作中，我们使用了一个高度非线性的光纤在相对较短的传输条件下的非线性信号失真的实验仿真在长距离传输条件下考虑无相位调制的时域非电信应用。分析了FrOFDM子载波对非线性失真的抑制作用，证实了FrOFDM子载波对非线性失真有很大的抑制作用。
Fractional orthogonal frequency division multiplexing (FrOFDM) exhibits considerable flexibility in the axis of multiplexing and a medium characteristic between OFDM and Nyquist optical time division multiplexing. FrOFDM subcarrier effect on nonlinear distortion in long haul transmission has not experimentally been verified. In this work, we used a highly nonlinear fiber under relatively short transmission conditions for experimental emulation of nonlinear signal distortion under long haul transmission conditions considering no phase modulation in time domain fornon-telecomapplication. Weexaminedthesuppressioneffectonthedis- tortion and confirmed that, FrOFDM subcarriers greatly suppress nonlinear distortion.
