(a) Leaky coaxial cable (LCX) structure; (b) propagation scenario of MIMO using two LCXs in the tunnel; (c) nonstationary 3D LCX-MIMO channel model in the tunnel: single-bounce non-line-of-sight (NLoS) path (−∙∙−), line-of-sight (LoS) path (−∙−); (d) randomly distributed scatters (×) on the wall and roof of a tunnel with length L = 50 m, width W = 5 m, and height H = 3 m.
