Abstract :
A brief introduction to the 2-D geometrical theory of diffraction (GTD) propagation prediction model (PPM) is presented. The author describes the application of this model to predicting channel phase, signal attenuation versus frequency, and the use of the fast Fourier transform to predict the channel impulse response from the GTD PPM predictions. The signal delay and delay spread values are computed. The results provide a powerful addition to the tools available to the RF engineer for digital system performance predictions
