Abstract

Abstract

Considering the modulation technique and multiple-access topology for indoor Visible Light Communication (VLC), two Multi-dimensional Carrierless Amplitude and Phase (Multi-CAP) modulation schemes are proposed in this paper, namely, DC biased Optical Multi-CAP (DCO-MCAP) and Unipolar optical Multi-CAP (U-MCAP). The design object is modeled as a mini-max optimization problem with a non-constraint condition named Perfect Reconstruction (PR), which can be solved by the quadratic programming algorithm. Only real and unipolar signals can be intensity modulated, therefore several modifications are performed in CAP VLC systems accordingly. A DC bias added to the signal and a pair of new samples including a zero padding to mark signal polarity are adopted to obtain unipolar signal respectively. According to Lambertian reflection model and considering light of sight link corrupted by Additive White Gaussian Noise (AWGN), the theoretical Symbol Error Rate (SER) of DCO-CAP/MCAP and U-CAP/MCAP are derived and corroborated by Monte Carlo simulations. Meanwhile, the performance of three kinds of dimensional (2D, 3D, 4D) optical CAP systems are analyzed and compared in the room in size of 5 m5 m3 m. The numerical results show that the error performance of optical Multi-CAP is superior to that of traditional two dimensional optical CAP with the same constellation, and the multi-CAP (3D or 4D) scheme can not only achieve approximate SER performance with respect to the same bandwidth efficiency, but also enable multiple access in VLC system. In addition, the effects of channel parameters on the system performance are evaluated which shows that the loss of SNR obviously presents positive relation with the increase of the radiation angle or the distance between the transmitter and the receiver.
