Abstract

Research in the field of optical wireless communications
(OWC) has led to significant advances
in high speed point-to-point communication
links, but there is much work to be done
in the area of multi-cell/multi-user OWC systems.
In order to make experimental research
in this area more approachable, we have developed
an SDR framework for OWC systems
and provided an open-source out-of-tree (OOT)
software library, namely gr-owc, that allows for
quick development and testing of novel OWC
techniques. In this paper we describe our recent
improvements to gr-owc, including the addition
of new OWC channel characteristics, modules
for DC-Biased Optical OFDM/OFDMA, and resource
allocation capabilities for custom hardware
that applies multi-color channels and enables
research in wavelength division multiplexing
(WDM) or wavelength division multiple access
(WDMA) systems. Furthermore, the hardware
deployment process is detailed to enable a
workflow that spans from simulated system analysis
to experimental evaluation.
