Superposed pulse amplitude modulation for visible light communication.
We propose and experimentally demonstrate a novel modulation scheme called superposed pulse amplitude modulation (SPAM) which is low-cost, insensitive to non-linearity of light emitting diode (LED). Multiple optical pulses transmit parallelly from different spatial position in the LED array and overlap linearly in free space to realize SPAM. With LED arrangement, the experimental results show t...
متن کاملHigh Efficient Modulation Techniques for In-Door Visible Light Communication
This paper describes state-of-the-art modulation techniques for visible-light-communications (VLCs) and proposes a new modulation technique, which is so-called generalized spatial pulse position modulation (GSPPM). Several modulation techniques, i.e., on-off-keying, pulse position modulation, pulse amplitude modulation and spatial modulation, are explained as background information for understa...
متن کاملOptical Non-Orthogonal Multiple Access for Visible Light Communication
The proliferation of mobile Internet and connected devices, offering a variety of services at different levels of performance, represents a major challenge for the fifth generation wireless networks and beyond. This requires a paradigm shift towards the development of key enabling techniques for the next generation wireless networks. In this respect, visible light communication (VLC) has recent...
متن کاملVisible Light Communication Systems for Optical Video Transmission
This article describes an optical wireless system based on visible light communication (VLC), which allows a video broadcasting to reach a bit rate of 1 Mbps, although this system can also be used for low-speed sensor interconnections. The main advantages of this technology are the robustness against EM interference, safety for human eye, and security against undesired network access. In this a...
متن کاملEnhanced Spatial Modulation of Indoor Visible Light Communication
In this study, we consider visible light communication in an indoor line-of-sight environment. It has been proved that among the multiple input multiple output (MIMO) techniques, spatial modulation (SM) performs better than repetition coding (RC) and spatial multiplexing (SMP). On the basis of a combination of SM and pulse amplitude modulation (PAM), here, we propose an enhanced SM algorithm to...
