Abstract :
The effects of directional antennas at the mobile unit on the Doppler power spectrum are investigated in this paper. The Doppler power spectral density (psd) functions at the mobile unit with a directional antenna employed at the mobile have been derived and presented. Two kinds of different antenna configurations at the base station are taken into our consideration. Namely, an omnidirectional antenna and directional antenna are employed
