  • Tuning method and system
    Patent number: 6545559
    Abstract: Tuning method for a combiner filter (2) in an antenna (3) near system for base station equipment is disclosed. Transmitted signals related to the combiner filter are compared with each other. A spectral analysis of each of the transmitted signals is performed. The spectral analysis results regarding magnitudes and/or phases of the signals are compared. The combiner filter (2) is tuned based on the analysis in an iteration procedure until the combiner filter is in accordance with predetermined conditions.
