The interest for short-reach links of the kind needed for inter-data-center communications
has fueled in recent years the search for transmission schemes that are simultaneously …

We present two schemes extending the Kramers-Kronig-receiver to polarization multiplexed
transmission. One of the schemes relies on the Stokes receiver and allows for complex …

The bound of the information transmission rate of direct current biased optical orthogonal
frequency division multiplexing (DCO-OFDM) for visible light communication (VLC) with …

Orthogonal frequency division multiplexing (OFDM) is attracting increasing attention in
optical communication systems, thanks to its inherent benefits such as high spectral …

In this article, we introduce two variants of energy efficient M-ary frequency-shift keying
(FSK) for low data rate/low power Internet-of-Things (IoT) applications. Both variants, ie, M …

We show that the spectral efficiency of a direct detection transmission system is at most 1
b/s/Hz less than the spectral efficiency of a system employing coherent detection with the …

Mutual interference is a crucial issue for the visible light communication (VLC) systems to be
addressed, including both co-channel interference (CCI) and inter-carrier interference (ICI) …

In this paper, a flexible non-orthogonal multiple access (NOMA) based optical orthogonal
frequency division multiplexing (OFDM) modulation scheme, called non-orthogonal hybrid …

In this paper, a novel modulation scheme called enhanced asymmetrically clipped DC-
biased optical OFDM (eADO-OFDM) is proposed to accommodate different demands of multi …

Optical-orthogonal frequency division multiplexing (O-OFDM) is an effective scheme for
visible light communications (VLC), offering a candid extension to multiple access (MA) …
