We analyze the performance of cooperative communication systems with opportunistic decode-and-forward for relaying and selection combining receiver at the destination. We derive an exact closed-form expression for the outage of the system over dissimilar Nakagami fading channels. Also, we study its asymptotic outage performance, based on which the optimum(More)
—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)
In this letter, we consider a cooperative communication network over Rayleigh fading channels. We assume that the amplify-and-forward (AF) and the selection decode-and-forward (SDF) opportunistic relaying methods are used and that the relay with the largest harmonic mean of the source-relay channel gain and the relay-destination channel gain is selected for(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)
