Modulation techniques for light fidelity (Li⁃ Fi) are reviewed in this paper. Li⁃ Fi is the fully
networked solution for multiple users that combines communication and illumination …

In the near future, the available radio-frequency (RF) bandwidth will not be sufficient to meet
the ever increasing demand for wireless access. Visible light communication (VLC) is an …

In this paper, three forms of orthogonal frequency division multiplexing (OFDM) designed for
intensity modulated/direct detection (IM/DD) optical systems are compared. These are …

Motivated by the looming radio frequency (RF) spectrum crisis, this paper aims at
demonstrating that optical wireless communication (OWC) has now reached a state where it …

A number of inherently unipolar orthogonal frequency division multiplexing (OFDM)
modulation schemes have been introduced recently in an attempt to improve the energy …

We study the information rates of unipolar orthogonal frequency division multiplexing
(OFDM) in discrete-time optical intensity channels (OIC) with Gaussian noise under average …

Visible light communication (VLC) is seen as a potential candidate for next generation
communication networks. In the last decade VLC has emerged out as complementary …

The field of visible light communication (VLC) has diverse applications to the end user
including streaming audio, video, high-speed data browsing, voice over internet and online …

Visible light communication (VLC) operates on optical intensity channels that are inherently
limited in bandwidth. Though Kramers-Kronig (KK) receivers have been considered as a …

Communication technology, explicitly remote Communication, remains one of the quickest
develo** advances in olden times. Some years ago, we progress from substantial huge …
