摘要

本文系统地分析了极化分复用非线性频分复用系统中离散特征值波动引起的相位旋转，并引入了一种先进的k-means方法来实现相位旋转均衡。monte - carlo数值模拟表明，与原来的k-means算法相比，采用改进的k-means方法可以快速获得初始质心和全局最优解，并带来一定的误码率增益。

Equalization of Polarization-Division-Multiplexed NFDM System Based on Advanced K-Means

In this paper, we systematically analyzed the phase rotation caused by discrete eigenvalues fluctuation for polarization-division-multiplexed nonlinear frequency division multiplexing systems, and introduced an advanced k-means method to implement phase rotation equalization. As demonstrated in numerical Montel-Carlo simulation, compared with the original k-means algorithm, by using the advanced k-means method, the initial centroids and global optimal solution could be obtained quickly, which brings a certain bit error rate gain.
