Ab$@uct-An adaptive antenna places nulls in its antenna pattern in the direction of the interfering sources. shifters. Adaptive antennas are a subset of smart antennas, and have received considerable interest in the recent wireless revolution. This paper presents a successful application of a genetic algorithm with an experimental antenna for placing a null in the direction of an interference s...

This paper, specifically written for GradCon ’99, presents an overview of the field of adaptive arrayprocessing. Beginning with a brief review of array synthesis theory, the concept of an adaptive array is introducedand defined. The broad field of adaptive array applications can be divided into two categories: adaptive signalprocessing for multiple access communication systems, and ...

In practical array systems, traditional adaptive beamforming algorithms are known to degrade if some of exploited assumptions on the environment, sources, or antenna array become wrong or imprecise. Therefore, the robustness of adaptive beamforming techniques against environmental and array imperfections and uncertainties is one of the key issues. In this paper, we present an overview of recent...
