A Comparison of Digital Beamforming and Power Minimization Adaptive Nulling Algorithms Using a Software Defined Radio Antenna Array

摘要

We compare adaptive nulling algorithms for digital beamforming (DBF) and non-DBF arrays. These algorithms will be implemented on a DBF array made from software defined radios. Results show that these techniques can achieve desirable signal to interference ratios that are comparable, and as such, implementing techniques applicable to non-DBF array are more cost effective.
