space time frequency coding-alamouti scheme

In this paper, we study a decode-and-forward twoway 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 sele

In this paper, we propose a distributed Alamouti space-time code (DASTC) for two-way relay networks employing a single amplify-and-forward (AF) relay. We first derive closedform expressions for the approximated average sum-rate of the propose

In this letter, we consider a half-duplex amplify-andforward two-way relaying network consisting of two sources with each having a single antenna and one relay having two antennas. For such a system, a distributed orthogonal space-time block code (
