Abstract

Presents a study of the required resolution to reject interference in a DBF antenna system for mobile satellite communications. The results obtained showed that the degradation of the null depth corresponded to the increase in the quantization noise caused by reducing the A/D converter word length. As the result of the paper, the A/D converter word length can be determined by the required null depth.<>
