We study quasi-spatially periodic signals (QSPSs) as a class of input signals of interest, which maintain their shapes quasi-periodically (with a phase change and a time shift) during propagation in an optical fibre. Instead of the computationally expensive nonlinear Fourier transform (NFT), the property of quasi-periodic shape invariant could be used as an alternative for decoding at the receiver. In this paper, properties of QSPSs and the signal design problem are studied, including the trade-off between various system parameters.
我们研究类准周期空间分布信号（QSPS）作为感兴趣的输入信号，它们在光纤中传播时保持准周期形状（相位变化和时间移位）。与计算成本较高的非线性傅里叶变换（NFT）不同，可以使用准周期形状不变的性质作为接收器处解码的替代方法。本文研究了 QSPS 的性质和信号设计问题，包括各种系统参数之间的权衡。
