Amplitude Only Linear Array Synthesis with Desired Nulls Using Evolutionary Computing Technique
Keywords:
Beam width, direction of arrival, firefly algorithm, side lobe levelAbstract
Beamforming is a desirous technique in wireless communication by which the desired signal is filter spatially from the interference environment. In this paper, the Firefly algorithm (FFA) is used to demonstrate such beamforming characteristics in linear arrays using amplitude only technique. The amplitude only technique is effectively employed with the FFA to synthesize the linear arrays with desired radiation characteristics. The generated radiation patterns have single and multiple nulls with no constraint imposed on beam width or side-lobe level. The beam steering characteristics are also studied using the same methodology.
