Design of wideband beamforming using particle swarm optimization

Beamforming is a signal processing technique by which an array of receivers sensitive to signals from all directions can be processed to form one larger more sensitive receiver that can identify which direction signals originate. In this paper the wideband beamforming using Tapped delay line will be investigated. Some applications in wireless communication systems need to design beamformer with a specified response like a sidelobe level less than threshold level or forming a null response points in interference direction or jamming frequency. So, we need to design optimal beamforming using optimization technique to achieve a desired response. In this paper, an evolutionary optimization technique, in specific, particle swarm optimization (PSO) will be used to design different examples on wideband beamforming.
