On the Cross Correlation Properties of MIMO Wideband Channels under Nonisotropic Propagation Conditions

Figure 5

PSD of UWB channels, MS moves in the positive direction of the -axis ((a), (b)) and -axis ((c), (d)), two antenna types employed at the MS, nonisotropic propagation (Laplacian or von-Mises distributed), and isotropic environment (uniformly distributed).

(a) Helical antenna

(b) Rectangular antenna

(c) Helical antenna
