“…The limitations of MIMO technology have motivated research on other techniques, and in particular, on cooperative communication systems that implement relay techniques acting as virtual multiple antennas [5], [6]. A cooperative relay technique in the uplink of a cellular system is known as a multiple-access relay channel (MARC) [7]- [9]. Spatial diversity was introduced to overcome the fading problem in securing wireless data streams to some extent [10].…”

In a wireless cooperative network, system reliability can be improved by introducing network coding (NC) for transmitting data packets from user to destination through relay nodes. At the destination, a decoding strategy is required to recover the original data packets. The use of NC in cooperative networks has been intensively studied in previous works in terms of the conventional model for two users and a single relay in a network. However, the network model cannot act as a virtual multiple-input multiple-output system, and a multi-user multi-relay network model could be used in a real system. Therefore, this paper proposes an improved model of two network decoding strategies, selection with soft combining (SSC) and selection with hard combining (SHC), for multi-user multi-relay cooperative networks. Users are classified based on their channel conditions, with better signal-to-noise (SNR) ratio sources being viewed as strong users, and others as weak or moderate users in the decoding strategies. To evaluate the performance of the proposed model, we first derive the bit error probability expressions for each strategy as a function of SNR and then evaluate the performance using numerical simulation for a Rayleigh fading channel. Simulation results show that SSC outperforms SHC. Furthermore, the improvement in network performance is achieved either by having a higher modulation level or using incremental relaying as the signal reception method at the destination.

“…However, the research on the multi-way relay systems with PNC just arose quite lately [14], [15]. In [16], an opportunistic scheduling scheme was proposed to construct the transmission protocol for the multi-way relay systems with PNC; five time slots were spent for transmission in a multi-way relay system with three source nodes.…”

In this paper, we propose a novel scheduling scheme which can be employed for multi-way relay systems. This new scheme is based on the physical-layer network coding (PNC). To evaluate our proposed scheme, the bit-error-rate (BER) and throughput metrics are analyzed for the multi-way relay systems enduring both channel fading and additive white Gaussian noise (AWGN). Moreover, numerous Monte Carlo experiments are undertaken to compare our proposed new scheduling scheme with other existing strategies. The simulation results demonstrate that our proposed scheme is much more efficient than other existing methods.Index Terms-Physical-layer network coding (PNC), scheduling, throughput analysis.
