| description | Visible light communications (VLCs) have attracted significant attention in recent years, where the novel concept of user-centric (UC) VLC based on amorphous cells (A-Cells) exhibits extra benefits compared with conventional circular cells. The construction of A-Cells relies on the knowledge of the users' positions; hence, the intrinsic amalgamation of VLC and positioning becomes important. Therefore, we propose a novel hybrid positioning technique by beneficially combining the low-complexity of triangulation-based positioning and the high accuracy of fingerprinting, in order to support A-Cell-assisted UC VLC under practical light-emitting diode linearity constraints with clipping distortion and noise. Our simulation results demonstrate that the proposed technique is capable of achieving a much higher positioning accuracy than triangulation at a lower complexity than fingerprinting, where the resultant system throughput is similar to that of perfect positioning. |
