Reduced Complexity Digital Back-Propagation Methods for Optical Communication Systems
Antonio Napoli,Zied Maalej,Vincent A. J. M. Sleiffer,Maxim Kuschnerov,Danish Rafique,Erik Timmers,Bernhard Spinnler,Talha Rahman,L.D. Coelho,Norbert Hanik +9 more
TL;DR: Two proposals to reduce the hardware complexity required by digital back-propagation are discussed, one confirms and extends published results for non-dispersion managed link, while the second introduces a novel method applicable to dispersion managed links, showing complexity reductions in the order of 50% and up to 85%, respectively.

On the Mitigation of Optical Filtering Penalties Originating From ROADM Cascade
Talha Rahman,Antonio Napoli,Danish Rafique,Bernhard Spinnler,Maxim Kuschnerov,Iveth Lobato,Benoit Clouet,Marc Bohn,Chigo Okonkwo,Huug de Waardt +9 more
TL;DR: In this article, the authors proposed and analyzed possible configurations for the mitigation of these penalties in optical domain using optical wave shaper (WS), including one WS in every ROADM node allowing transmission of 28 and 32 GBd signals, which are QPSK, 8-QAM, or 16QAM modulated, through a cascade of 32 and 14 WSS filters.
Journal ArticleDOI
The role of small cell technology in future Smart City applications
Antonio Cimmino,Tommaso Pecorella,Romano Fantacci,Fabrizio Granelli,Talha Rahman,Claudio Sacchi,Camillo Carlini,Piyush Harsh +7 more
TL;DR: It is demonstrated that the novel concept of small cell fully meets the emerging communication and networking requirements of future Smart Cities, based on small cells, in the framework of a future smarter and user‐centric perspective of forthcoming 4G mobile technologies.
Journal ArticleDOI
Digital Compensation of Bandwidth Limitations for High-Speed DACs and ADCs
Antonio Napoli,Mahdi M. Mezghanni,Talha Rahman,Danish Rafique,Robert Palmer,Bernhard Spinnler,Stefano Calabro,Carlos Castro,Maxim Kuschnerov,Marc Bohn +9 more
TL;DR: A novel digital preemphasis algorithm to compensate for the electrical bandwidth limitations at the transceiver also by taking into account the quantization noise introduced by the signal digitalization, and can considerably increase the maximum transmittable symbol rate for the case of advanced modulation formats.
