An SVM-Based Detection for Coherent Optical APSK Systems With Nonlinear Phase Noise

Abstract: A support vector machine (SVM)-based data detection is proposed for coherent optical fiber amplitude phase-shift keying (APSK) communication systems where the nonlinear phase noise is the main system impairment. The performances of the detection with SVMs are investigated for three different 16-APSK modulation formats. In addition, three transmission scenarios with dispersion being considered or not are adopted to simulate and analyze the performances. Compared with the traditional two-stage maximum-likelihood… Show more

“…The Voronoi diagram by contours has been used to assist the clustering-based demodulation stage when symbol distortion is severe [11]. An approximation to its definition may be introduced as the proximity regions to a set of objects in a bidimensional plane.…”

“…Due to its robustness, SVM is believed to separate received symbols to correct classifications well during nonlinearity equalization process. An SVM classifier was first trained and applied in nonlinearity compensation for combating nonlinear phase noise in amplitude phase-shift keying (APSK) system [14]. Recently, five SVM methods including: 1) the one versus rest (OvR) where the multi-classifiers are built one by one considering the rest belonging to the other class with the concept of binary SVM; 2) the symbol encoding; 3) the binary encoding (BE) is based on whether each bit of label feature is 0 or 1; 4) the constellation rows and columns (RC); and 5) the in-phase and quadrature components (IQC) were investigated and IQC indicates the optimal results among all five in terms of computing resource and hardware storage [15].…”

“…Another set of digital approaches for nonlinear compensation is based on machine learning techniques. Some popular implementations are based on Artificial Neural Networks (ANNs) ( [7]) and Support Vector Machines (SVMs) ( [8], [9]). In [10] techniques based on nonlinear state-space based Bayesian filtering and Gaussian Mixture Models (GMMs) are presented.…”
