“…In order to address this research problem, authors have proposed a multi‐armed bandit relay selection technique to dynamically obtain the optimal mapping. In Reference 17, the authors have studied the average AoI of physical layer network coding enabled TWRN with and without automatic repeat requests. Further, the authors have identified the key differences between AoI and conventional performance metrics within TWR networks.…”

Motivated by the timely need for fresh updates in time‐critical applications, this paper investigates the AoI‐driven UAV trajectory optimization for a two‐way relay network. The non‐linear simultaneous wireless information and power transfer (SWIPT) power‐splitting (PS) technique is used to provide the energy required for UAV communication considering hardware impairments. Amalgamating derived outage probability, AoI expression is obtained to evaluate data timeliness and its performance trade‐offs. Then, we optimize the trajectory of the UAV while minimizing the AoI performance within the given discretized time slot. The impact of the system parameters, that is, size of the status update, PS factor, outage probability, and UAV's position, on the AoI performance are extensively investigated.

“…I NTEREST in cooperative communications and relay networks has increased dramatically over recent years since such systems provide diversity advantages with relatively low complexity [1]- [11]. The Two-Way Relay Network (TWRN), where two terminals exchange information with the assistance of a relay, has received much attention in the literature [5] [6] [7] [9] [11] since it achieves higher transmission efficiency and network throughput than One-Way Relay Network (OWRN) [12]. In particular biderectional relaying has been found of interest to 6G systems [1] and IoT applications [2].…”

In this work, we consider a selective Detect-and-Forward (a symbol based decode-andforward) (DetF) multi-relay two-way network employing differential MPSK with regularized Weighted Decision Feedback Differential Coherent (WDFDC) receivers. Regularized WDFDC receivers based on a regularized linear predictor (RLP) were proposed for one-way relay networks where it was shown to mitigate the performance loss due to decision feedback error propagation and intermittent transmission between relay nodes and the destination.This paper introduces regularized WDFDC receivers for two way selective DetF relay networks, employing various protocols with and without network coding, and using multiple relays. For each protocol, an optimal destination threshold is derived to decide if a relay transmits or remains silent. Furthermore, analytical performance bounds, providing insights to the effects that cause degradation, are also derived. Extensive simulation results demonstrate that the use of network coding achieves higher bandwidth efficiency, but suffers an error rate performance loss. Diversity gains can be achieved when the number of relays increases. However, repeated transmissions from the same relay do not yield extra diversity gains.

“…The performance of SM and FD under the influence of self-interference has been investigated by deriving analytical equations for Symbol Error Rate, outage probability, and capacity [19]. In [20][21][22][23], the performance of FD has been evaluated using the Bit Error Rate (BER), ergodic capacity, and probability of Outage Performance (OP).…”

In this paper, Physical Layer Network coding (PLNC)-Spatially Modulated Full-Duplex (SMFD) nodes based two-way/bidirectional cooperative wireless relay network is proposed. The PLNC-SMFD-based system is a viable technology in the field of next-generation wireless networks to enhance spectral efficiency. In the proposed system model, both the source nodes and relay nodes are employed with 2 × 2 antenna configurations where 2 bits of information are exchanged between the source nodes through a relay node. Transmit antenna selection at the source nodes is based on the incoming bitstreams. For instance, the transmit antenna is selected at PLNC-SMFD nodes based on the data symbols of the Most Significant Bit (MSB). Whereas the selected transmit antenna sends the Least Significant Bit (LSB) bit of data symbol at any time instance. Further, the self-interference at the transmitting and receiving nodes is modeled as Gaussian with the thermal noise power as a variance. The Bit Error Rate (BER) analytical expressions for both the upper and lower bound are derived in a Rayleigh Fading channel background. It has been graphically shown that the BER performance of the proposed system analyzes the effect of self-interference.
