Capacity of optical wireless communication channels

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2020
Optical wireless communications are realized by modulating the intensity of a light source and detecting intensity fluctuations at the receiver. This mode of operation, known as intensity modulation and direct detection (IM/DD), is simple to implement in practice.

Optical wireless communication for backhaul and access

2015 European Conference on Optical Communication (ECOC), 2015
We highlight new applications for optical wireless communication (OWC) as a mobile backhaul for WiFi, LTE and 5G and as a new access technology in the Internet of Things (IoT) where it enables secure and reliable communications at low latency.

Use Cases for Optical Wireless Communication

Optical Fiber Communication Conference, 2018
We present results from trials in three promising uses cases for optical wireless communication (OWC): Mobile backhaul, industrial wireless, and indoor Li-Fi. We point out specific requirements and illustrate performance through measurements in typical scenarios.

On the capacity of indoor optical wireless communications

IEEE Communications Letters, 2006
In this letter, the capacity of an optical wireless communications system in an indoor environment is investigated. We consider various modulation schemes, e.g. pulse-position modulation (L-PPM), differential pulse-position modulation (L-DPPM) and differential amplitude pulse-position modulation (AtimesL-DAPPM).

Optical wireless MIMO communications (OMIMO)

IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005
We propose optical wireless multiple-input multiple-output (OMIMO) communications to achieve high speed transmission with a compact transmitter and receiver. In OMIMO, by using zero forcing (ZF), we can eliminate the other signal interferences transmitted from other optical transmit antennas.

Optical Wireless Communications for Heterogeneous DARS

2018
Distributed autonomous robotic systems (DARS) can provide essential support to human task forces in a variety of missions. Maintaining reliable communications on these mobile networks is critically important for cooperative autonomy. Radio-frequency is the common wireless communication technology employed for task coordination.
