Studies of optical wireless communications: random orientation model, modulation, and hybrid WiFi and LiFi networks [article]

Ardimas Andi Purwita, University Of Edinburgh, Harald Haas, Majid Safari, Wasiu Popoola
In addition, a random blockage model must be investigated as LiFi signals can be blocked by opaque objects.  ...  These features are also the main features of WiFi, and WiFi is predicted to carry the majority of global mobile data traffic in the future.  ...  The reason for explaining the enhanced versions of PAM-SCFDE is because of the lack of further studies on PAM-SCFDE, which is in contrast to the number of studies of the IM/DD-based OFDM systems.  ...

Optical broadband in-home networks for converged service delivery [article]

Y Yan Shi, AMJ Ton Koonen, E Eduward Tangdiongga
I enjoyed our international dinner, birthday party, Friday movie night and all travels in EU, USA and China... I am also grateful for other former ECO people, Dr. Bas Huiszoon and Dr.  ...  Solomon Abraha for sharing the office room and making  ...  Therefore, the IM-DD scheme results in a cost-effective system without raising special requirements for the POF transceiver design.  ...
