First Claim
1. A cosite analysis system which comprises:
- means for interactively designing an antenna tower for placement of one or more antennas on the tower;
means for interactively designing wireless communication circuits;
means for interactively relating the antennas on the tower to the wireless communication circuits; and
RF analysis means for simulating the wireless communication circuits with their related antennas and for generating reports on the possible interference between the wireless communication circuits;
wherein the wireless communication circuits include two or more transmitters and one or more receivers and wherein the RF analysis means includes;
means for determining a minimum susceptibility to interference of the one or more receivers at each transmitter;
means for separately considering each transmitter as a victim transmitter and for determining and storing a highest order intermodulation product generated as a result of interference between the victim transmitter and each other transmitter individually with a power level sufficient to exceed the minimum susceptibility at the victim transmitter; and
means for separately considering each transmitter as a victim transmitter and for determining the intermodulation products generated as a result of interference between the victim transmitter and all of the at least one other transmitter, each other transmitter having a leakage power to the victim transmitter, the one of the other transmitters with the lowest leakage power to the victim transmitter being the minimum leakage transmitter, the intermodulation products being determined up to the highest order intermodulation product stored for the minimum leakage transmitter and victim transmitter.

Abstract
An antenna cosite analysis system with: interactive displays for i) designing an antenna tower for placement of one or more antennas on the tower, ii) designing wireless communication circuits, and iii) relating the antennas on the tower to the wireless communication circuits; and an RF analysis system for analyzing interference between the wireless communication circuits. A process for determining intermodulation interference between transmitters and one or more receivers includes the steps of: determining a minimum susceptibility of the receivers; determining a highest order intermodulation product generated as a result of interference between the victim transmitter and each other transmitter with a power level sufficient to exceed the minimum susceptibility of the one or more receivers at the victim transmitter; and determining the intermodulation products generated as a result of interference between the victim transmitter and the other transmitters, the intermodulation products being determined up to the highest order intermodulation product of a minimum leakage transmitter-victim transmitter pair. Also disclosed is a process for determining intermodulation interference in a receiver, an apparatus for determining intermodulation interference in transmitter, and an apparatus for determining intermodulation interference in a receiver.
