Conference paper

Experimental analysis of pilot-based equalization for probabilistically shaped WDM systems with 256QAM/1024QAM

In Optical Fiber Communication Conference 2017 — 2017, pp. 1-3

Pilot based equalization is studied in a 5x10 Gbaud WDM transmission experiment. The equalization is independent of the modulation format and is demonstrated for 256/1024QAM with uniform and probabilistically optimized distribution using an optimized pilot insertion rate of 2-5%.
