摘要: The degrees of freedom (DoF) the two-user multiple-input and multiple-output (MIMO) broadcast channel (BC) without state information at transmitter (CSIT) is studied, in which each receiver equipped with reconfigurable antennas capable choosing a subset receiving modes from several preset modes. Under general setting arbitrary number transmit antennas, modes, linear sum DoF completely characterized by developing an optimal blind interference alignment scheme obtaining matching upper bound available for any coding strategy.
