Cet article propose un schéma d'optimisation déterministe du placement de modèles pilotes basé sur l'algorithme de génétique quantique (QGA) qui vise à améliorer les performances de l'estimation des canaux clairsemés dans les systèmes de multiplexage par répartition orthogonale de la fréquence (OFDM). En minimisant la propriété d'incohérence mutuelle (MIP) de la matrice de détection, l'optimisation du placement du modèle pilote est modélisée comme la solution d'un problème d'optimisation combinatoire. QGA est utilisé pour résoudre le problème d'optimisation et générer un modèle pilote optimisé qui peut efficacement éviter les pièges optima locaux. Les résultats de la simulation démontrent que la méthode proposée peut générer une matrice de détection avec un MIP plus petit qu'une recherche aléatoire ou l'algorithme génétique (GA), et que le modèle pilote optimisé fonctionne bien pour l'estimation de canaux clairsemés dans les systèmes OFDM.

Abstract: This paper proposes a deterministic pilot pattern placement optimization scheme based on the quantum genetic algorithm (QGA) which aims to improve the performance of sparse channel estimation in orthogonal frequency division multiplexing (OFDM) systems. By minimizing the mutual incoherence property (MIP) of the sensing matrix, the pilot pattern placement optimization is modeled as the solution of a combinatorial optimization problem. QGA is used to solve the optimization problem and generate optimized pilot pattern that can effectively avoid local optima traps. The simulation results demonstrate that the proposed method can generate a sensing matrix with a smaller MIP than a random search or the genetic algorithm (GA), and the optimized pilot pattern performs well for sparse channel estimation in OFDM systems.
