Indoor Sensor Data Transmission for Energy-Saving Buildings
Authors: ,
Abstract: Sensor data transmission for indoor sensor network for energy saving buildings can be accomplished by indoor visual light communication (VLC) technology using the white LED originally equipped for energy saving illumination. In this paper, new blind equalization methods are proposed for enhanced data rate and robustness against multipath effect, DC bias and impulsive noise which are crucial obstacles in indoor VLC. Based on the property that the Gaussian kernel of lagged cross-correlation of probabilities (LCCP) method has the inherent immunity against those obstacles, decision feedback (DF) approach is applied for data rate improvement. From the results of the simulation, DF version of LCCP algorithm yielded about 8 dB of MSE performance enhancement showing rapid compensation for multipath effect undisturbed by impulsive and DC bias noise in the indoor VLC environment.
