Meta-DSP: A Meta-Learning Approach for Data-Driven Nonlinear Compensation in High-Speed Optical Fiber Systems

xinyu xiao, Zhennan Zhou, Bin Dong, Dingjiong Ma et autres

Nonlinear effects in high-speed optical fiber systems fundamentally limit channel capacity. While traditional Digital Backward Propagation (DBP) with adaptive filters addresses these effects, its computational complexity remains impractical. Data-driven solutions like Filtered DBP (FDBP) reduce complexity but critically lack inherent generalization: Their …

Learning effective nonlinear operator for high speed optical compensation system

xinyu xiao, Hang Yang, Dingjiong Ma, Jie Sun et autres

Optical communication systems, which form the backbone of modern communication networks, are often hindered by impairments arising from both linear and nonlinear Kerr effects during signal transmission. While Chromatic Dispersion Compensation (CDC) mitigates linear distortions, existing digital signal processing (DSP) algorithms focus …
