Performance analysis of a VLC system with a new light source and joint step-by-step mapping spatial modulation
A new type of light source in the visible light communication (VLC) system was adopted to realize the illumination and data transmission functions simultaneously.Also,a joint step-by-step mapping spatial modulation method based on spatial modulation and red,green,and blue (RGB) LED was proposed.The...

| description | A new type of light source in the visible light communication (VLC) system was adopted to realize the illumination and data transmission functions simultaneously.Also,a joint step-by-step mapping spatial modulation method based on spatial modulation and red,green,and blue (RGB) LED was proposed.The new light source consisted of white LED and one or more sets of RGB LED,where white LED provided only illumination and RGB LED was only used for communications.The color of RGB LED was controlled by power allocation and the color quality of the new light source was evaluated by color rendering index (CRI).Moreover,the bit error rate (BER) performance of the joint step-by-step mapping spatial modulation scheme with direct current optical orthogonal frequency division multiplexing (DCO-OFDM) at the receivers was also analysed.Simulation results show that the power of RGB LED can be adaptively adjusted according to different requirements of communication and illumination to meet the needs of different scenarios.The VLC system can achieve good BER performance with appropriate light group layout and direct current paranoia. |
