Cellular Coverage Optimization for Indoor Visible Light Communication and Illumination Networks

In visible light communication (VLC) systems, cellular networks are required for large indoor environment and built as a kind of new networks when combining the LED illumination, named communication and illumination networks (CIN). The co-channel interference (CCI) between adjacent cells leads to large areas of communication dead zones. Users covered by access points (APs) within illumination r...

Enhanced 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...

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...
