Abstract

The invention relates to a method of combining several signals and to a base station (200) for combining several signals in a radio network. The base station (200) comprises an antenna (206), modulating means (202) for generating and modulating carrier waves, and transmitters (201) for generating signals, which are used to modulate the generated carrier waves. The signals are transmitted modulated using the antenna (206) to the carrier wave. The modulating means (202) modulate two or more signals to their own carrier waves. The base station comprises means (203) for amplifying the carrier waves modulated by the signals, and means (204) for passively combining the carrier waves modulated by the signals to the same antenna (206) after amplification.
