Measurement and Statistical Analysis of Distinguishable Multipaths in Underground Tunnels

<div>Comparison of PDPs under NLOS conditions: (a) comparison of multipath conditions under LOS and NLOS conditions with a fixed transmission power of 10 dBm and distance of 10 m; (b) comparison of multipath conditions with different distances; (c) comparison of multipath conditions in “L” and “U” type environments.</div>
