by Muhammad Usman Hadi, Jacopo Nanni, Olivier Venard, Geneviève Baudoin, Jean-Luc Polleux, Pier Andrea Traverso and Giovanni Tartarini

Advances in Science, Technology and Engineering Systems Journal, Volume 4, Issue 3, Page # 156–163, 2019; DOI: 10.25046/aj040321

Abstract:

The article proposes a Digital Predistortion (DPD) methodology that substantially meliorates the linearity of limited range Mobile Front Haul links for the extant Long-Term Evolution (LTE) and future (5G) networks. Specifically, the DPD is employed to Radio over Fiber links that contrive of Vertical Cavity Surface Emitting Lasers (VCSELs) working at 850 nm. Both, Memory…
