Hardware Acceleration Techniques for 3D Urban Field Strength Prediction

Planning and optimization of radio networks are active research areas. Therefore, both fast and accurate radio wave propagations predictions are required. To fulfill those requirements the authors propose specialized algorithms on ordinary graphics cards. They present an efficient algorithm for determining the visibility between objects. Therefore, they exploit the discrete pixel structure on Graphics Processing Units (GPU). This leads to a tremendous acceleration of up to 140 times compared to a version on a CPU.
