“…The author in Liu (2016) analyse the performance of single-relay two-way relay network (TWRN) while multiple relays TWRN are investigated in Cheng et al (2018). But the transmission reliability of TWRN is the main challenge which is overcome by the incorporation of multiple antenna system in relaying (Thakur and Chattopadhyay, 2020). This is useful to combat the effect of multipath fading in the wireless networks.…”

In this paper, a 5G mobile communication system is considered with cooperative environment. The mobile and base-station node communicate with each other through a number of amplify-and-forward (AF) relays. The users have multiple antennas while each relay has a single antenna. The radio-frequency (RF) transceiver chain associated with each antenna element leads to increased hardware complexity. This challenge is reduced by efficient utilisation of RF front ends in the proposed wireless system. The paper proposes an RF chain selection technique which enables the selection of RF front end with maximum received signal-to-noise-ratio (SNR). The outage probability is derived for proposed mobile communication system. Further, system ergodic capacity, energy efficiency and average end-to-end SNR are evaluated. As compared to the conventional random selection approach, this algorithm aims to achieve higher capacity and higher average end-to-end-SNR. At 16 dB SNR, system capacity improves by 52% with proposed algorithm rather than conventional random selection.

In this paper, the security of two-way relay communications in the presence of a passive eavesdropper is investigated. Two users communicate via a relay that depends solely on energy harvesting to amplify and forward the received signals. Time switching is employed at the relay to harvest energy and obtain user information. A friendly jammer is utilized to hinder the eavesdropping from wiretapping the information signal. The eavesdropper employs maximal ratio combining and selection combining to improve the signal-to-noise ratio of the wiretapped signals. Geometric programming (GP) is used to maximize the secrecy capacity of the system by jointly optimizing the time switching ratio of the relay and transmit power of the two users and jammer. The impact of imperfect channel state information at the eavesdropper for the links between the eavesdropper and the other nodes is determined. Further, the secrecy capacity when the jamming signal is not perfectly cancelled at the relay is examined. The secrecy capacity is shown to be greater with a jammer compared to the case without a jammer. The effect of the relay, jammer, and eavesdropper locations on the secrecy capacity is also studied. It is shown that the secrecy capacity is greatest when the relay is at the midpoint between the users. The closer the jammer is to the eavesdropper, the higher the secrecy capacity as the shorter distance decreases the signal-to-noise ratio of the jammer.
