Hybrid positioning for the amorphous-cell assisted user-centric visible light downlink
Hybrid positioning for the amorphous-cell assisted user-centric visible light downlink
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.

Abstract
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.
