Abstract

We have developed a DBF signal processor with application specific integrated circuits (ASICs). We show a hardware implementation of this signal processor and experimental results. The DBF also has the advantage of adaptive array antenna signal processing. This allows the nulls of an antenna radiation pattern to be steered in the directions of interference signals. As a result, degradation due to multipath interference can be effectively reduced. We show the configuration of the adaptive array antenna suitable for mobile satellite communication and the experimental results using the DBF implemented with ASICs
