| contents | Analysis of wireless propagation using a novel 3D Ray- tracing acceleration technique Adolfo Escobar Lorena Lozano Hector Cadavid Manuel F. Cátedra Ingeniería ray tracing propagation models Acceleration techniques wireless communications The rapid growth in wireless communications has led to the need for an effective way to evaluate the radio propagation. Dense urban areas and indoor spaces tend to be complex environments that require a lot of obstacles to be modeled. In such environments, the radio propagation is an extremely complex phenomenon and ray tracing techniques have been widely used to analyze these problems. However, the main drawback of ray tracing algorithm is it slowness. Therefore, the ray tracing process should be performed using techniques that improve the efficiency of the computations. This paper presents a new ray tracing acceleration technique that combines AZB and octree techniques to subdivide the space. This new technique was validated by propagation measurements in two hospital environments and the maximum error encountered for measured and calculated values was below 8%. The new technique reduces the computation time by half in comparison to AZB technique. But, as the number of interactions increases, computational time increases as well. 2013 artículo científico 0123-3033 https://www.redalyc.org/articulo.oa?id=291329166004 en http://www.redalyc.org/revista.oa?id=2913 Ingeniería y Competitividad application/pdf Universidad del Valle Ingeniería y Competitividad (Colombia) Num.2 Vol.15 |
