Detailed Documentation
Based on the classical Walfish-Bertoni transmission loss prediction model, we can utilize PDF (Probability Density Function) and CDF (Cumulative Distribution Function) simulation programs to study transmission loss in wireless communications. These simulation programs feature statistical modeling of path loss components including rooftop diffraction and multi-screen scattering effects, implemented through Monte Carlo methods or analytical probability calculations. The implementation typically involves parameterizing urban environmental factors such as building heights and street widths, then generating statistical distributions of signal attenuation. Such simulations help researchers better understand signal transmission processes in wireless communication systems and facilitate performance evaluation and optimization of wireless channels through probabilistic analysis of link reliability and coverage probability.
