Enumerative Sphere Shaping for Rate Adaptation and Reach Increase in WDM Transmission Systems (1907.01881v1)
Published 3 Jul 2019 in eess.SP, cs.IT, and math.IT
Abstract: The performance of enumerative sphere shaping (ESS), constant composition distribution matching (CCDM), and uniform signalling are compared at the same forward error correction rate. ESS is shown to offer a reach increase of approximately 10% and 22% compared to CCDM and uniform signalling, respectively.
