Doppler Spectra for F2F Radio Channels With Moving Scatterers

Based on a ring, a disk, and an elliptical scattering models, the power spectral densities (PSDs) are derived and investigated for fixed-to-fixed (F2F) propagation scenarios with moving scatterers located at a predefined geometry of the models. The velocity distributions of the moving scatterers are assumed to follow uniform, exponential, and mixed Gaussian, and the scatterers can be moving with either low or high speed. The results show that the one ring, the disk, and the model in [14] are very close in describing the PSDs for the F2F radio channels. Moreover, different shape factors have little effect on the PSDs in the disk model. As the shape factor is large enough, the disk model tends to be the same as the one-ring model. The PSDs derived from the elliptical model are different from the one ring and disk models because the scatterers are not only distributed nearby the transceiver, but also distributed along the path between the two ends of the transceiver.
