  • Method for determining radio transmitter sites with signals that may potentially interfere with an intended signal at a radio receiver site
    Patent number: 5410736
    Abstract: A method for conducting radio transmission systems interference studies based on the prior art two-step process of conducting a simple analysis on all potentially interfering systems to eliminate those clearly not causing interference into radio receiver under study, and then conducting a detailed analysis on the remaining systems. The new method replaces the first step in the prior art system with a method using pre-calculated average terrain elevations over a geographic block for determining whether the loss should be calculated using a smooth terrain calculation method with a simulated single knife edge diffraction obstacle in the path, or a rough terrain calculation method that substitutes a pre-calculated block roughness factor in place of the path roughness factor, and then also substitutes a new effective antenna height for the actual antenna height in the propagation loss calculations.
