Kernel Adaptive Filtering for Nonlinearity-Tolerant Optical Direct Detection Systems

Lu Zhang, Oskars Ozolins, Rui Lin +16

Kernel adaptive filtering (KAF) is proposed for nonlinearity-tolerant optical direct detection. For 7x128Gbit/s PAM4 transmission over 33.6km 7-core-fiber, KAF only needs 10 equali…
