Abstract-This paper presents a relay activation scheme designed for joint channel-and-network (JCN) coded systems relying on an iterative decoding. A primary focus is on proposing criteria of the relay activation to find the best user combination for cooperative relaying, which exploits extrinsic information transfer (EXIT) chart analysis. We will demonstrate that the EXIT chart aided relay activation scheme is capable of reducing the probability of outages, despite increasing the effective throughput of network.Index Terms-User cooperation, network coding, channel coding, iterative decoding, multi-hop, cooperative relaying, EXIT chart analysis. I. INTRODUCTIONUser cooperation has attracted significant research attention owing to its spatial diversity benefits [1], [2]. Relaying or multi-hop transmissions constitute the simplest form of user cooperation. However, due to the creation of the broadcast and cooperation phases, they achieve a high diversity gain at the cost of a factor two multiplexing loss. To overcome this deficiency, the adoption of network coding has been studied, where we multiplex several users' information by their algebraic superposition over a finite field [3], [4]. As a benefit of the network coding, the above-mentioned half duplex multiplexing loss is mitigated without sacrificing the diversity gain. The designs of joint channel-and-network (JCN) codes and their iterative detection have been investigated in [5]-[7]. In [5], a simple triangular topology conceived for two-user cooperation was combined with beneficial channel codes. As further advances, two-way relay channels (TWRC) and multiple-access relay channels (MARC) were investigated in [6] and [7], respectively, where a turbo-like code was constituted for transmissions over the TWRC and MARC in order to achieve a high diversity gain.The primary focus of this paper is on finding beneficial relay activation criteria for a simple triangular topology. In sophisticated JCN coded systems, extrinsic information transfer (EXIT) chart analysis may be involved for visualizing the convergence behavior of the iterative detection scheme [8], [9]. Against this background, the novel contribution of this treatise is that an EXIT-chart-aided relay activation scheme is proposed for a low-complexity XOR assisted JCN code.

“…Two)way wireless communication was considered in [12], [13], and [14]. In the DF scheme of [12], distributed turbo codes were used for protection: each node receives data from the relay and directly from the other node over two orthogonal channels; joint decoding is used for reconstruction for each node. The benefit of combining NC with convolutional codes via DF was shown in [13].…”

The key idea is to channel encode each source's message by using a high)performance non)binary turbo code based on Partial Unit Memory (PUM) codes to enhance the bit)error)rate performance, then reduce the energy consumption and increase spectrum efficiency by using network coding (NC) to combine individual nodes' messages at the relay before forwarding to the destination. Two simple and low complexity physical layer NC schemes are proposed based on combinations of received source messages at the relay. We also present the theoretical limits and numerical analysis of the proposed schemes. Simulation results under Additive White Gaussian Noise, confirm that the proposed schemes achieve significant bandwidth savings and fewer transmissions over the benchmark systems which do not resort to NC. Theoretical limits for capacity and Signal to Noise Ratio behaviour for the proposed schemes are derived. The paper also proposes a cooperative strategy that is useful when insufficient combined messages are received at a node to recover the desired source messages, thus enabling the system to retrieve all packets with significantly fewer retransmission request messages.

Abstract-This paper investigates jammer selection in a twoway decode-and-forward (DF) relay network with imperfect channel state information (CSI). The proposed scheme enables an selection of one conventional relay and two jamming nodes to enhance communication security against eavesdropper. The conventional relay assists two sources to exchange their data via a DF protocol. The two jamming nodes are used to create interference signals to confuse the eavesdropper. Furthermore, the asymptotic performance of proposed scheme is analyzed in detail. Under the assumption that the relay can decode received signals perfectly and when the jamming power is higher than that of source nodes, we find that the proposed scheme has a high secrecy performance which is almost independent of the position of the eavesdropper.
