Abstract
This paper evaluates the ACRi Blind Beamforming (ABB) smart antenna algorithm which addresses the significant problem caused by high-power transmitters located in close proximity to users. Current solutions are overwhelmed by the rapid increase in number and variety of strong interference sources. ABB requires less computational complexity than standard algorithms, making it feasible to be added to current and next-generation systems, and provides a highly adaptive and reliable interference-resistant communications environment. Simulations show that ABB automatically nulls jamming signals that are 20 dB to 40 dB stronger than the user signal, achieving close to the theoretically best performance despite being a blind solution (no information required about the jammer or user signal) and its low computational requirements. Systems with a limited number of antennas are evaluated because legacy and current generation systems have as little as two antennas.
