A new and efficient ray-tracing method based on the combination of the image theory and the binary space partitioning (BSP) algorithm is presented. The efficiency of the method allows a full three-dimensional implementation of the geometrical optics and the uniform theory of diffraction (GO/UTD). The main feature of the method is the possibility of analyzing the radio channel in general enclosed spaces, including indoor, outdoor and mixed indoor/urban environments. This approach can be used for developing efficient engineering tools for the analysis of the radio channel in wireless and mobile communications systems. Several results that show the accuracy and efficiency of the method are presented.
