LED-ID (light emitting diode - identification) system typically uses line of sight (LOS) channels to achieve high data rate and bright illumination. In LOS channel, however, the LED-ID system has very narrow coverage. In cellular networks, the relay station has been introduced to improve system throughput and coverage. Accordingly, new optical relay scheme is essential to support multi-hop transmission in relay-assisted LED-ID networks. In this paper, effects of shadow region problem are… CONTINUE READING
