Dans cette lettre, une méthode d'accélération du lancer de rayons (RT) basée sur la minimisation des rangs est proposée. RT est un outil général utilisé pour simuler des environnements de communication sans fil. Cependant, la simulation prend du temps en raison du grand nombre de calculs de rayons. Cette lettre se concentre sur l'interpolation de cartes radio comme approche d'accélération. Les méthodes conventionnelles ne permettent pas d'estimer de manière appropriée la variation à courte portée provoquée par l'évanouissement par trajets multiples. Pour surmonter le manque de méthodes conventionnelles, nous adoptons une interpolation basée sur la minimisation des rangs. Une simulation informatique utilisant un logiciel RT commercial a révélé que la précision d'interpolation de la méthode proposée était supérieure à celle des autres méthodes d'interpolation de cartes radio et que la simulation RT peut être accélérée environ cinq fois plus rapidement avec un taux manquant de 0.8.

Abstract: In this letter, a ray tracing (RT) acceleration method based on rank minimization is proposed. RT is a general tool used to simulate wireless communication environments. However, the simulation is time consuming because of the large number of ray calculations. This letter focuses on radio map interpolation as an acceleration approach. In the conventional methods cannot appropriately estimate short-span variation caused by multipath fading. To overcome the shortage of the conventional methods, we adopt rank minimization based interpolation. A computational simulation using commercial RT software revealed that the interpolation accuracy of the proposed method was higher than those of other radio map interpolation methods and that RT simulation can be accelerated approximate five times faster with the missing rate of 0.8.
