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 includes one or more antenna arrays composed of several elements, one or more channel units having components for phasing the signal to be transmitted and received by the antenna array in such a way that the gain from the antenna array is the greatest in the desired directions. Each channel unit includes components for searching for the incoming directions and delays of the received signal components, and components for controlling the phasing components on the basis of the 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.
