Space-Time Correlation for Three-Dimensional MIMO Channel Model Using Leaky Coaxial Cables in Rectangular Tunnel

Figure 3

Amplitude correlation function (CF: LoS + NLoS): (a) different moving speed and time delay (t = 0 s, d = 0.7λ); (b) different time and time delay ( = 360 km/h, d = 0.7λ); (c) different region Rx1 in tunnel and LCX spacing (τ = 0.5 ms, t = 0.06 s,  = 360 km/h).
