| Abstract: | The Doppler spectral density is revealed to be generally asymmetrical in the real wireless propagation environment.This conclusion drawn from the analysis of the impact on the Doppler spectral density due to the dominant incoming signal components and the spatial change of the dominant components in the land mobile communication Rician mutipath channel.Finally the theoretical analysis and the simulation results are given. |

| Keywords: | Mobile communications Rician channel Doppler spectrum density Multipath fading |
