چکیده
A deterministic model for spherical wave propagation in microcellular urban environment is presented. This methodis based on ray tracing and uniform theory of diffraction. The various ray contributions includes the diffraction from corner of obstacle, reflection from ground and direct wave. According to the height of transmitting station, different ray paths will be presented in the received signal. Calculation is carried out using hard and soft polarization. Results can be used for the planning of new cellular system. Key wordsRay tracing, UTD, urban environment.

Propagation Prediction Model for Land Mobile Communication in Microcellular Environment
The propagation channel is the principal contributor to many of the problems and limitations that degrades the performance of mobile radio systems. One obvious example is multipath propagation which is a major characteristic of the mobile radio channels, which severely affects the performance of digital systems by reducing the carrier-to-interference ratio. Thus accurate characterization of the...

Ray-tracing and UTD (Uniform Theory of Diffraction) techniques are already widely applied to site-specific radio propagation modeling for wireless applications. This paper briefly presents the software tool Radio-Tracer that uses efficient algorithms to calculate dynamically the exact visibility graph of an environment taking into account the position of both transmitter and receivers and the m...
متن کاملSimulation in Urban Environment of a 3d Ray Tracing Propagation Model Based on Building Database Preprocessing
The analysis and simulation of electromagnetic (EM) wave propagation represent a crucial task in planning cellular networks for mobile communication. When an adequate building database is available, deterministic 3D ray tracing techniques are quite useful and accurate to face this problem, but since their computational complexity is time consuming, a preprocessing step is necessary. Such a step...

متن کاملAn Efficient Algorithm for Radiowave Coverage Prediction in Urban Microcells
This work presents an algorithm to perform radiowave coverage predictions in urban environments using the Uniform Theory of Diffraction (UTD). The ray-tracing algorithm is based on the image theory for a quasi-3D environment. Multiple reflections and diffractions are considered through the separation of multipath components into four different classes, used to determine the scattered field. The...
