A method and system is disclosed for reducing interference in a wireless communication system utilizing an antenna array. The antenna array uses one or more signal channels for communicating with one or more mobile terminals. First, at least one channel is assigned as an empty channel in which no desired signal is carried so as to provide a representation of all relevant interference. Since the spatial characteristics of the empty channel and the regular signal channels should be very similar, the spatial signature of the signal channels is analyzed based on the interference received on the empty channel and the desired signals received on at least one signal channel. The analyzed spatial signature is then used for reducing the interference on all signal channels. |
