Abstract

A Doppler estimation based on a statistical analysis of the channel power variations is proposed for the frequency division duplex (FDD) mode of Universal Mobile Telecommunication Systems (UMTS). Its implementation is considered in both cases of constant power and closed-loop power controlled transmissions. Performance is analyzed in terms of velocity estimation error under various conditions of speed, estimation delay and signal-to-interference-plus-noise ratio (SINR). The influence of a SINR-based power channel estimation is also taken into account. Results show the reliability of this Doppler estimation technique that yields estimates with less than 15 km/h error in a velocity range from 0 km/h to 100 km/h. Results also present the impact of the closed-loop power control on the Doppler estimation reliability
