Abstract:
Communication systems and methods are disclosed. A number of interference sources are obtained based on received signals. A communication is performed using a plurality of antennas and a transmission directivity of the antennas is controlled when transmitting signals. At least null-steering from among null-steering and beam-forming is performed in relation to the transmission directivity of the antennas, when the number of interference sources is less than a first threshold value. Only the beam-forming is performed from among the null-steering and the beam-forming in relation to the transmission directivity of the antennas, when the number of interference sources is greater than the first threshold value.
