Search for: [Description = "The flat\-top radiation pattern is necessary to form an appropriate beam in a sectored cellular network and to pro vide users with best quality services. The flat\-top pattern offers sufficient power and allows to minimize spillover of signal to adjacent sectors. The flat\-top sector beam pattern is relied upon In sectored cellular networks, in multiple\-input multiple\-output \(MIMO\) systems and ensures a nearly constant gain in the desired cellular sector. This paper presents a comparison of such optimization techniques as real\-coded genetic algorithm \(RGA\) and particle swarm optimization \(PSO\), used in cellular networks in order to achieve optimum flat\-top sector patterns. The individual parameters of flat\-top sector beams, such as cellular coverage, ripples in the flat\-top beam, spillover of radiation to the adjacent sectors and side lobe level \(SLL\) are investigated through optimization performed for 40◦ and 60◦ sectors. These parameters are used to compare the performance of the optimized RGA and PSO algorithms. Overall, PSO outperforms the RGA algorithm."]
