“…The ANC scheme is essentially a form of linear self-interference cancelation with the use of a priori known information. In [21], the authors derive both the outage probability and diversity-multiplexing tradeoff in a multiple source-destination pairs system, where the relay performs the ANC. In [22], the relay deploys a cooperative and multicast ANC scheme so that two destinations can use the interfered signals to recover the desired packet.…”

In this paper, we propose a generalized analog network coding (GANC) scheme for a non-orthogonal multiple-access relay channel (MARC), where two sources transmit their information simultaneously to the destination with the help of a relay. In the GANC scheme, the relay receives interfered signals from the two sources and generates signals to be transmitted with a relay function. We focus on the design of the optimal relay function to achieve the minimum pair-wise error probability (PEP) of the system. Specifically, we first covert the relay function optimization problem to a transformation matrix (TM) design problem by presenting the received complex signals as signal matrices composed of real and imaginary parts. Then, we propose an optimization criteria, i.e., maximizing the minimal squared Euclidean distance (MMSED), to improve the PEP performance, since the PEP is determined by the Euclidean distance of the received constellation at destination. Next, we prove that the MMSED can be equivalently converted to a convex problem by introducing an intermediate matrix. We solve this convex problem by using the Lagrangian method and obtain the closed-form expression of the optimal TM. We further improve the PEP performance by optimizing transmission power of the two sources. Simulation results show that the proposed GANC scheme has a better PEP performance compared to other alternative schemes.

“…The outage performance of SPM-NC-CC has been studied in [14] for the scenario of twouser cooperation. The authors of [15] analysed the outage performance of a superposition-modulated CC (SPM-NC-CC) system supporting multiple SN-DN pairs sharing a common RN. However, it was assumed in [15] that the destination node (DN) cancels the effects of the unwanted SNs' signals by perfectly recovering them.…”

Abstract-We consider a network, where multiple sourcedestination pairs communicate with the aid of a half-duplex relay node (RN), which adopts decode-forward (DF) relaying and superposition-modulation (SPM) for combining the signals transmitted by the source nodes (SNs) and then forwards the composite signal to all the destination nodes (DNs). Each DN extracts the signals transmitted by its own SN from the composite signal by subtracting the signals overheard from the unwanted SNs. We derive tight lower-bounds for the outage probability for transmission over Rayleigh fading channels and invoke diversity combining at the DNs, which is validated by simulation for both the symmetric and the asymmetric network configurations. For the high signal-to-noise ratio regime, we derive both an upperbound as well as a lower-bound for the outage performance and analyse the achievable diversity gain. It is revealed that a diversity order of 2 is achieved, regardless of the number of SN-DN pairs in the network. We also highlight the fact that the outage performance is dominated by the quality of the worst overheated link, because it contributes most substantially to the network coding noise. Finally, we use the lower bound for designing a relay selection scheme for the proposed SPM based network coded cooperative communication (SPM-NC-CC) system.

In this paper, a cooperation system suitable for networks with multiple users is proposed. In the first phase of the cooperation, the user who has correctly decoded the source signal and has the best channel condition is selected as the relay. Given that the best relay selected by one source–destination (s‐d) pair may also be selected by other pairs, complex field network coding (CFNC) is adopted by the relay in the second phase, to provide diversity gains for the s‐d pairs simultaneously. The number of channels used is reduced, thus increasing the network throughput. Additionally, this system makes up for the performance loss of the traditional CFNC cooperation in large‐scale networks by achieving more diversity gains. Especially, a closed‐form expression of the average signal error probability (SEP) is derived for small‐scale networks, while an upper‐bound estimation is given for larger networks. It is demonstrated that the system achieves full diversity and is robust. To improve the SEP performance of the system, the receiver is modified, and the results demonstrate desirable average SEP performance. Finally, the analytical results are validated by numerical simulations. © 2014 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
