Image Sensor Based Visible Light Communication and Its Application to Pose, Position, and Range Estimations

This study introduces an image sensor based visible light communication (VLC) and its application to pose, position, and range estimations. There are two types of visible-light receiver: a photodiode and an image sensor. A photodiode is usually used as a reception device of VLC, and an image sensor consisting of a large number of pixels can also be used as a VLC reception device. A photodiode d...

Indoor Location Estimation Using Visible Light Communication and Image Sensors

High power white LEDs are expected to replace the existing lighting technologies in near future which are also suggested for visible light communication (VLC). We proposed an algorithm for high precision indoor positioning using lighting LEDs, VLC and image sensors. In the proposed algorithm, four LEDs transmitted their three-dimensional coordinate information which were received and demodulate...

Experimental Demonstration of 4×4 MIMO Wireless Visible Light Communication Using a Commercial CCD Image Sensor

Visible light communication (VLC) is a kind of wireless optical communication technique using light-emitting diode (LED) light [1-4]. It is an area of growing interest with the worldwide growth of the LED illumination market. VLC is emerging as a candidate for future indoor wireless communications because in indoor applications VLC has several advantages over conventional radio frequency (RF) w...

High 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...
