Abstract:
In this paper, a joint design of axis alignment and positioning under non-line-of-sight (NLoS) indoor conditions or 60 GHz millimeter-wave (mmWave) wireless local area networks/wireless personal area networks (WLANs/WPANs) is proposed. First, an axis alignment scheme called rotation vector method is proposed, in which the newly joining station (STA) rotates x- and y-axis based on the proposed two-step-wisely refinement principle to make its axis aligned with the personal basic service set (PBSS) control point/access point (PCP/AP). Second, the equipotential region (ER) based positioning approach is carried out for the newly joining STA in a conference room rich with obstacles. Finally, our proposed joint design is evaluated both through theoretical analysis and simulation. The results show that the number of rotation is reduced by the proposed axis alignment scheme without cost of the alignment accuracy under a same condition, and the positioning accuracy is increased by the proposed joint design.
