Doubling the Spectral Efficiency with EVM as the Objective Function for Training Neural Networks in Non-Orthogonal Visible Light Communications Systems

Not Accessible

Your library or personal account may give you access

Abstract

We experimentally demonstrate, for the first time, that neural network detector performance can be enhanced by using EVM as the objective loss function. This method allows bandwidth compression up to 50% in non-orthogonal VLC systems.
