摘要： The present invention relates to a node in a wireless communication system, which comprises at least one transceiver unit, a first and a second antenna function. The antenna functions comprise a first and a second port connection. The transceiver unit is arranged to communicate by means of at least one frequency band. Each port connection is connectable to said transceiver unit via electrical signal delays of different magnitudes. In a first mode of operation, a certain resulting main radiation lobe is acquired when the antenna functions are receiving or transmitting for each frequency in the frequency band. Said main radiation lobe has a main pointing direction with a certain angular direction in azimuth and elevation with respect to a fixed angular direction. The angular direction for every certain frequency is different from the angular direction for any other frequency.

摘要： A communications device for separating source signals provided by M signal sources includes an antenna array comprising N antenna elements for receiving at least N different summations of the M source signals. A respective in-phase and quadrature module is connected downstream to each antenna element for separating each one of the N different summations of the M source signals received thereby into an in-phase and quadrature component set. A blind signal separation processor forms a mixing matrix comprising at least 2N different summations of the M source signals, with each in-phase and quadrature component set providing 2 inputs into the mixing matrix. The mixing matrix has a rank equal up to 2N. The desired source signals are separated from the mixing matrix by the blind signal separation processor.
