Opportunistic Relay Selection for Decode-and-Forward Two-Way Relaying under Outdated Channel State Information
—The Channel State Information (CSI) plays a significant role in wireless Relay Selection (RS) systems. Due to the time variation of channels, the CSI in the data transmission phase may differ (i.e., is outdated) from that in the relay selection phase. Addressing this issue, the Decode-andForward (DF) Two-Way Relaying (TWR) network is considered, and the impact of outdated CSI on the system pe...
متن کاملSubcarrier Allocation for Multiuser in Two-Way OFDMA Relay Networks using Decode-and-Forward Relaying
A two-way relay network provide improved spectral efficiency compared with a conventional one-way relay network by using either superposition coding or network coding. OFDMA network provides imptoved performance by adaptive resource allocation. In this paper, we propose a adaptive subcarrier allocation for a multiuser two-way OFDMA relay network. In the proposed algorithm, subcarriers are alloc...
متن کاملMaximum euclidean distance network coded modulation for asymmetric decode-and-forward two-way relaying
Abstract: Network coding (NC) compresses two traffic flows with the aid of low-complexity algebraic operations, hence holds the potential of significantly improving both the efficiency of wireless two-way relaying, where each receiver is collocated with a transmitter and hence has prior knowledge of the message intended for the distant receiver. In this contribution, network coded modulation (N...
متن کاملA Study of Half-Duplex Asymmetric Two-Way Decode-and-Forward Relaying Using Relay Selection
This paper examines the information theoretic metric of outage probability for a decode-and-forward (DF) based asymmetric two-way relay transmission (i.e. the two source terminals have different target rates). We first characterize the achievable rate region of a conventional three-node network. After that the conventional three-node scenario is analyzed in terms of outage probability and the c...
متن کاملOutage Performance of Decode-and-Forward in Two-Way Relaying with Outdated Channel State Information
In this paper, we analyze the outage behavior of decode-and-forward relaying in the context of selective two-way cooperative systems. First, a new relay selection metric is proposed to take into consideration both transmission rates and instantaneous link conditions between cooperating nodes. Afterwards, the outage probability of the proposed system is derived for Nakagami-m fading channels in ...
