This paper reconsiders the design of blind interference alignment (BIA) for $K$-user MISO interference channel in which each receiver is equipped with a reconfigurable antenna of preset $M_k\geq 3$ modes. Beyond the degree of freedom (DoF)-oriented BIA (D-BIA) design proposed by Lu et al., we further take into account the frequency of mode switching within one supersymbol frame. Even though every...
This paper considers the BIA implementation of K-user multiple-input single-output (MISO) interference channel (IC) without CSIT, in which each transmitter is equipped with Mk ≥ 3(k = 1, …, K) antennas and each receiver has a reconfigurable antenna with Mk preset modes. Stemmed from the existing DoF-oriented BIA (D-BIA) scheme, we propose a new BIA scheme to reduce the frequency of mode switching...
This paper studies the blind interference alignment (BIA) of a heterogeneous 3-user 2x1 broadcast channel (BC). In the BC considered, the transmitter equipped with two antennas broadcasts information symbols to three receivers with each possessing a unique reconfigurable antenna. By heterogeneous it means that the three 2x1 links connecting the transmitter and the three receivers experience independent...
