Polarization Demultiplexing by Independent Component Analysis
Xiaobo Xie, Fatih Yaman, Xiang Zhou, Guifang Li · IEEE Photonics Technology Letters · 2010
Independent component analysis has been applied to polarization demultiplexing for coherent optical fiber communications. Polarization-multiplexed quadrature phase-shift keying and quadrature amplitude modulated signals were successfully demultiplexed by a tensor-based algorithm without using any knowledge of the modulation format.
