Designing of an Indoor Visible Light Communication Transceiver for Data Transmission using White LED

Abstract

Abstract: In this paper, a prototype of full-duplex indoor  Visible  Light  Communication  (VLC) transceiver  is  designed  to  demonstrate  an  optical wireless  system  based  on  Universal  Serial  Bus (USB) port for data transmissions using white Light Emitting  Diode  (LED).  Based  on  VLC  technology, the  designed  system  consists  of  transmitters  and receivers can achieve data rate of 161.2 Kbps error free at the distance of 92 cm between two computers for  real-time  text  and  image  transmission  over indoor  environment.  Experiment  results  show  that for text transmission, symbol error rate (SER) does not  vary  data  rate  at  some  transmission  distances, whereas  for  image  transmission,  minimum  square error (MSE) and peak signal to noise ratio (PSNR) indicate  that  the  received  image  and  transmitted image were almost similar.
