Abstract:

Visible Light Communication (VLC) is an emerging field in Optical Wireless Communication (OWC) which utilizes the superior modulation bandwidth of Light Emitting Diodes (LEDs) to transmit data. The VLC application generally adopts Manchester and miller codes to reach dc-balance, enhancing signal reliability. So the Manchester and Miller encoder is an important part of VLC emitter section. In this paper, we have presented the architecture of VLC and designed the combined Manchester and Miller encoder. The behavior of Manchester and Miller encoder is realized by derivation of VHDL code in Xilinx ISE 13.1 software. The paper also aims to make comparative study of two coding technics used for outdoor VLC. The synthesis result shows that integrated Manchester and Miller encoder indicates successful function.
