Graphics Hardware Accelerated Field Strength Prediction for Rural and Urban Environments

Acceleration techniques on graphics hardware for field strength prediction algorithms are presented. We identify some basic building blocks of common propagation algorithms and propose methods which can be very efficiently implemented on graphics processing units. We show that the use of such acceleration techniques leads to huge speedups in the evaluation time of propagation algorithms.
