Smart antenna based on coherent adaptation methods in WCDMA reverse link

Abstract

The objective of this thesis is to study the efficient adaptation methods for smart antenna in WCDMA reverse link. First, we review the channel structure of WCDMA reverse link and exploit the structure of uplink physical channels to find the important information for implementation of smart antenna. Second, we study the spatial channel models. We presents the power-controlled spatial channel model to accept the effect of the closed-loop fast power control. Next, we present the algorithm structure applicable to real-time implementation in WCDMA reverse link. To make the convergence speed of weight adaptor fast, the coherent adaptation methods are adopted. The performance analysis is given by computer simulation. The various simulation environments are included to analyze the performance. Also the performance is verified by the real-measurement data from our smart antenna testbed.
