Coded Modulation with APSK for OFDM-Based Visible Light Communications
Coded modulation with APSK is proposed for OFDM-based VLC systems. Simulation results show that the proposed scheme achieves better performance than conventional QAM counterpart in both DCO-OFDM and ACO-OFDM systems, while similar complexity is maintained. OCIS codes: (060.2605) Free-space optical communication; (060.4080) Modulation.
متن کاملReview of Ofdm Modulation Scheme for Indoor Visible Light Communication System
Visible light communication (VLC) system for small range transmission uses visible spectrum which provides illumination simultaneously. Designing cost of light emitting diodes was reduced in order to make this communication possible. A modulation technique which can effectively employ the bandwidth is orthogonal frequency division multiplexing (OFDM) technique. This technique has a unique form ...
متن کاملA Review: Visible Light Communication using MU-MIMO-OFDM
Visible Light Communication (VLC) is an approach which uses LEDs (Light Emitting Diodes) for lightning as well as for providing an opening for economical higher data transfer rate setup for wireless communication, which can be used as an alternative for effective and efficient communication that can merge with the demand for higher transfer rate wireless communication. In this paper, we take an...
متن کاملSuperposed 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...
