Abstract: The present invention relates to a method of analyzing interference between heterogeneous wireless communication systems, including receiving, by an interference analysis unit, interference parameters from a parameter input unit; receiving, by the interference analysis unit, polarized information from a polarized information input unit and calculating a Polarized Mismatch Loss Factor (PMLF) between a transmission antenna of an interference transmitter and a reception antenna of a victim receiver; and analyzing, by the interference analysis unit, an interference influence of the interference transmitter on the victim receiver based on the interference parameters and the PMLF. In accordance with the present invention, an interference influence between heterogeneous wireless communication systems using different polarized waves can be precisely analyzed by incorporating a loss characteristic according to a polarized mismatch between transmission and reception antennas into the interference influence.

Abstract: Disclosed herein are a method and apparatus for analyzing interference in the time-space dimensions. The apparatus includes an evaluation area partition unit configured to partition an evaluation area into lattices in order for a receiver to determine whether a permitted interference level at which interference needs to be accepted is satisfied or not and an interference analysis unit configured to spatially evaluate the amount of interference in each of the lattices based on a result of temporal evaluation of the amount of interference in each of the lattices.
