“…Firstly the receiver must identify and select a set of multipath components to recombine in the RAKE structure. This typically involves searching for paths, or using cross-correlation techniques such as those described in [11]. The second stage, which we address in the remainder of this paper, is to track the delays of the multipath components through time.…”

Spatial transmit diversity schemes are now well integrated into third-generation cellular mobile communication system specifications. When DS-CDMA-based technology is deployed in typical macro- and microcell environments, multipath diversity and spatial diversity may be exploited simultaneously by a 2D RAKE receiver. The work presented in this paper focuses on taking advantage of spatial transmit diversity in synchronising the 2D RAKE structure. We investigate the use of coherent and noncoherent techniques for tracking the timing parameters of each multipath component. It is shown that both noncoherent and coherent techniques benefit from transmit diversity. Additionally the performance gap between these two techniques increases with the number of antennas
