摘要：

In recent years, Pre-Rake combining technique has become a hot topic of research as it decreases the complexity of the portable mobile unit, while achieving the same multipath diversity effect of the Rake receiver. In practice, the error in channel estimation in Pre-Rake system occurs due to time variability in mobile radio channel. In this paper, we present pre-rake performance under imperfect channel estimation due to time variability in TDD system, depending on Doppler Frequency and compare it with the ideal Pre-Rake system.
