Using the Uniform Theory of Diffraction to Analyze Radio Wave Propagation along Urban Street Canyons for Device-to-Device Communication

This paper examines the propagation of radio waves in so-called urban street canyons through formulations based on Geometrical Optics (GO) and Uniform Theory Diffraction (UTD). As this type environment comprises a flanked by tall buildings more or less equally spaced both sides (creating canyon-like morphology), estimating attenuation that signals may experience these scenarios is crucial to planning device-to-device (D2D) wireless communication. In sense, results obtained analysis GO/UTD (in horizontal plane containing transmitter receiver) are validated comparison with experimental measurements, showing good agreement. work demonstrates how use GO/UTD-based can contribute simpler computationally efficient D2D mobile communication systems which considered be modeled as an canyon comprising rectangular equispaced buildings.
