ABSTRACT:
A method for interference analysis in a mobile radio network having an adaptive antenna in at least some of its cells and including traffic channels and control channels, includes calculating an interference ratio of interference of one traffic channel of an adaptive antenna of a first cell to a user signal in a traffic channel of an adaptive antenna of a second cell. The interference ratio of interference in a traffic channel of a first cell not having an adaptive antenna to a user signal is calculated in a traffic channel of a second cell having an adaptive antenna. The interference ratio of interference in a control channel of a first cell with or without an adaptive antenna to a user signal is calculated in a control channel of a second cell with or without an adaptive antenna relative to the entire surface of the cell without considering the adaptive antenna in each of these cells.
