Abstract. The accurate estimation of mixing matrix is critical for blind separation, for solving the problems of traditional methods such as bad robustness and low accuracy, a method based on statistical modal is proposed. The generalized Gaussian mixture modal is used to fit the distribution of single-source-points, a new objective function for clustering is obtained from the view of maximum likelihood estimation. Constrained particle swarm optimization is used to optimize the objective function, by which the mixing matrix is estimated. This method is applicable to determined and underdetermined blind source separation. The simulation shows that the proposed method has higher estimation accuracy and is more robust than traditional methods.

“…Therefore, it is desirable to design a high-performance and efficiency algorithm in the conformal array synthesis problem. Due to the flexibility and efficiency of the evolutionary optimization algorithms such as the genetic algorithm, ant colony optimization, and particle swarm optimization, they are widely employed for the antenna array pattern synthesis in recent years [14][15][16][17][18][19][20][21][22][23][24][25]. Moreover, in many practical scenarios, it is required that single array antenna can radiate multiple radiation patterns [26][27][28][29][30].…”

Abstract-A method of designing a cylindrical conformal array with shaped-beam and reconfigurable dual-beam using a modified particle swarm optimization algorithm is proposed in this paper. The proposed algorithm is easy to implement and efficient to be used in synthesizing conformal arrays with digital attenuators and digital phase shifters. Moreover, the proposed synthesis has taken the actual active element patterns into account, which can reduce the error between computation and realization. Good agreement can be obtained between the desired patterns and the synthesized patterns.

“…In [11], a technique for designing a planar array of parasitic dipoles that modify the pattern of a λ/2-dipole placed λ/4 over a ground plane was described. This method, that synthesizes a pencil beam pattern with good performance, uses the Particle Swarm Optimization (PSO) [12][13][14][15][16][17][18][19][20] tool of method of moments program FEKO [21] to optimize the length of each parasitic dipole and the distance between the planar array and the ground planes as well as the interspacing of the parasitic elements. In this model, the antenna works as a set of scattering elements in a mutual coupling environment localized in a plane.…”

Abstract-In this paper, several simple antenna designs based on the use of an active dipole placed above a ground plane with an array of parasitic dipoles are presented. The parasitic dipoles are used to modify the pattern of the active dipole yielding a pencil beam of moderate gain. The use of one active element provides a very simple feeding network that reduces the complexity of the antenna. The proposed technique optimizes the geometry and configuration of both active and parasitic elements. It is shown that the performance of the designed antennas is considerably better than that of a similar antenna without parasitic elements.
