Abstract

Smart antenna techniques have been proposed to increase channel capacity and enhance system performance of a base station in cellular and PCS applications. To date, most of the smart antenna research is focused on the development and analysis of smart antenna systems for uplink applications, i.e., the receive part of a smart antenna system. Not much research is done on developing smart antenna algorithms for downlink applications. In this paper, we shall present a new systematic technique for designing downlink weighting vectors for improving the downlink performance of a smart antenna system. The new method draws on the filter bank concept and provides a suboptimal solution to the difficult downlink weight design problem. With the computation complexity comparable to the so-called pseudo-inverse approach, our method always outperforms its counterpart, sometimes by a significant margin.
