Abstract
A base station receiver and a reception method in a CDMA cellular radio system includes, in each cell, at least one base station communicating with a plurality of mobile stations situated within its area. The base stations measure the direction angle of a signal arriving from each mobile station with respect to the base station, and communicate with the mobile stations using antenna beams that change in time. The angles of the greatest gain of the beams are adjusted according to signal components arriving from the mobile station. In order to provide detection of good quality without a great deal of calculation, the detection of the desired signal utilizes simultaneously several signals received from different mobile stations taking into account the incoming direction of the signals when selecting the signals.
