Abstract:
A base station equipment for receiving and transmitting a signal of a desired user, which signal to be received may arrive at the equipment along several different paths with several different delays, and which equipment comprises one or more antenna arrays (500) composed of several elements, one or more channel units (504-508), which channel unit comprises means (600-606) for phasing the signal to be transmitted and received by the antenna array (500) in such a way that the gain from the antenna array is the greatest in the desired directions, characterized in that the channel unit (504-508) comprises means (604) for searching for the incoming directions and delays of the received signal components, and means (604) for controlling the phasing means (600-606) on the basis of said information in such a way that the angle of the greatest gain of the antenna beams is deflected in the environment of the desired directions.
