Abstract :
The effects of directional antennas at the mobile unit on the Doppler power spectrum are investigated. The Doppler power spectral density (PSD) functions at the mobile unit employing a directional antenna have been derived and presented. These Doppler PSD functions were derived for both the omnidirectional and directional antenna cases at the base station.
