Visible light positioning has the potential to yield sub-centimeter accuracy in indoor environments, yet conventional received signal strength (RSS)-based localization algorithms cannot achieve this because their performance degrades from optical multipath reflection.

Extending fibre nonlinear interference power modelling to account for general dual-polarisation 4D modulation formats

no code implementations • 25 Aug 2020 • Gabriele Liga, Astrid Barreiro, Hami Rabbani, Alex Alvarado

In optical communications, four-dimensional (4D) modulation formats encode information onto the quadrature components of two arbitrary orthogonal states of polarisation of the optical field.
