Partial-response maximum-likelihood technique for indoor wireless visible light communication system

Abstract

In near future, the conventional electric lamps will be replaced by the white light emitting diode (LED) lamps because it offers many advantages such as low power consumption, long life time, small size, cool operation system. This work proposes the receiver design based on a partial-response maximumlikelihood technique for the indoor wireless visible light communication system, where a transmitter is placed on the ceiling, a receiver is on the table, and the signal transmission is based on the on-off keying intensity modulation. In addition, we also compare the performance between the proposed system and the conventional analog system in terms of bit-error rate at different data rates.
