—In this paper, we study a decode-and-forward two-way relaying network. We propose an opportunistic two-way relaying (O-TR) scheme based on joint network coding and opportunistic relaying. In the proposed scheme, one single " best relay " is selected by MaxMin criterion to perform network coding on two decoded symbols sent from two sources, and then to(More)
—Staggered fading pattern between different users is crucial to interference alignment without CSIT, or so-called blind interference alignment (BIA). This special fading structure naturally arises from heterogeneous block fading setting, in which different users experience independent block fading with different coherent times. Jafar et al. prove that BIA(More)
This paper first studies the homogeneous 3-user 2×1 broadcast channel (BC) with no CSIT. We show a sufficient condition for it to achieve the optimal 3 2 degrees of freedom (DoF) by using Blind Interference Alignment (BIA). BIA refers to the interference alignment method without the need of CSIT. It further studies the 2×1 broadcast network in which there(More)
