Názov: Optimal bit-and-power allocation algorithm for VLC-OFDM system.
Autori: Ling Wei, Hongming Zhang, Bingyan Yu
Zdroj: Electronics Letters (Wiley-Blackwell); 6/9/2016, Vol. 52 Issue 12, p1036-1037, 2p, 5 Graphs
Predmety: ORTHOGONAL frequency division multiplexing, VISIBLE spectra, ELECTROMAGNETIC interference, LIGHT emitting diodes, ADDITIVE white Gaussian noise
Abstrakt: An optimal bit-and-power allocation (BPA) algorithm for visible light communication-orthogonal frequency-division multiplexing (VLCOFDM) system is proposed and demonstrated. It is such notable that the signal noise in VLC-OFDM system is not addition white Gaussian noise and its power changes with the received signal power through experimental measurement. Thus the optimal Hughes-Hartog BPA algorithm based on variable noise power is presented. Compared with the traditional BPA algorithm, the experiment indicates that the proposed optimal BPA algorithm can achieve about 15.9% improvement of data rate for VLC-OFDM system.
