UNIB proposes PSO techniques to improve algorithms in communication systems

Juan Castañedo Galvlán, researcher at the Universidad Internacional Iberoamericana (International Iberoamerican University, UNIB), is participating in a study that explores and proposes several techniques to optimize the convergence, accuracy, and adaptability of PSO algorithms.

Particle swarm optimization (PSO), a computational technique inspired by the collective behavior of swarms, was proposed by James Kennedy and Russel Eberhart in 1995. It has since become an effective method for solving various optimization problems. The PSO simulates the social behavior of a swarm of particles in which each particle represents a competent solution in the search area. 

The particles move in the search area, adjusting their positions according to their experience and that of neighboring particles. Its purpose is to find the best solution by frequently updating the particle positions.

Therefore, the aim of this research has been to bring improvements in the field of adaptive equalization by exploring PSO techniques to improve the convergence, accuracy, and adaptability of PSO algorithms. The research studied the combination of PSO with other optimization algorithms, the introduction of adaptive mechanisms, the application of multi-objective optimization, and the use of the constraint factor approach and dynamic neighborhood topology.

Research results

The research determined that the best solution for adaptive filtering is HPSO, as it showed higher performance compared to other optimization techniques. This technique is efficient in channel equalization, taking advantage of its global search capability to improve equalizer coefficients and the performance of communication systems by reducing the effects of channel distortion and inter-symbol interference.
