Multiuser MIMO Indoor Visible Light Communication System Using Spatial Multiplexing

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...

In order to enhance the reliability of the indoor visible light MIMO wireless communication system and improve the ability of anti-interference between channels of the system, this paper introduces the new model of Space Shift Keying in the radio frequency communication into the visible light MIMO communication. The simulation analysis shows, the MIMO system of SSK has almost similar performanc...

A Hybrid Approach to Spatial Multiplexing in Multiuser MIMO Downlinks

In the downlink of a multiuser multiple-input multiple-output (MIMO) communication system, simultaneous transmission to several users requires joint optimization of the transmitted signals. Allowing all users to have multiple antennas adds an additional degree of complexity to the problem. In this paper, we examine the case where a single base station transmits tomultiple users using linear pro...

Indoor Localization Based on Visible Light Communication

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...
