These models are based on ray tracing technique or numerical. Slope UTD with convex hull model is a model which has less computation time, higher accuracy of prediction and based on ray tracing technique. S-UTD-CH model is used in multiple diffraction due to that this model gives more accurate results in less computation time. Obstacles can be modelled as knife edge, wedge or cylinder in ultra-high frequencies. Inner angle, structure type and relative permittivity constant and conductivity of obstacle and polarization type of electromagnetic wave change the relative path loss at the receiver. In the study, how building parameter changes the relative path loss is discussed. © 2015 IEEE.trinfo:eu-repo/semantics/closedAccessimpedance wedgeray tracing techniqueS-UTD-CH modelWave diffractionBalloonsCircular waveguidesElectromagnetic wave polarizationElectromagnetic wave propagationElectromagnetic wavesSignal processingBuilding parametersCoverage predictionImpedance wedgeMultiple diffractionRay-tracing techniqueRelative permittivityUltra-high frequencyWave diffractionsRay tracingimpedance wedgeray tracing techniqueS-UTD-CH modelWave diffractionBalloonsCircular waveguidesElectromagnetic wave polarizationElectromagnetic wave propagationElectromagnetic wavesSignal processingBuilding parametersCoverage predictionImpedance wedgeMultiple diffractionRay-tracing techniqueRelative permittivityUltra-high frequencyWave diffractionsRay tracingConference Object11311510.1109/SIU.2015.7130223
