—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)
Although the sufficient condition for a blindly interference-aligned (BIA) 2-user 2 × 1 broadcast channel (BC) in homogeneous fading to achieve its maximal 4/3 DoF is well understood, its counterpart for the general K-user 2 × 1 MISO BC in homogeneous block fading to achieve the corresponding 2K 2+K−1 (DoF) remains unsolved and is, thus, the focus of this(More)
