Abstract

This paper presents an analysis on the body-centric channel parameters classification for various compact 3 base station L-Shape configurations utilizing only a 2D-plane for installation. Four different L-Shape configurations (x-z/y-z plane) are studied (facing-front/side/back) by varying the position of the base stations in an indoor environment. Results and analyses highlight the variation of the channel parameters with respect to the orientation of the base station configurations and presence of the human subject. Channel parameters values (peak power delay profile (PDP)/rms delay spread sigma/Kurtosis) are reported for (line of sight (LOS): -65 to -50 dB/0.5-5 nsec/40-60) and (non-line of sight (NLOS): -80 to -65 dB/ 10-25 nsec/ 5-25). The 3D localisation accuracy obtained is highest (1-3 cm) for the x-z plane L-Shape configuration facing-front which has maximum number of LOS links (70%).The accuracy decreases by 1-2 cm for the x-z plane L-Shape configuration facing-back due to increase in NLOS links (70%) between the wearable antennas and the base stations.
