“…As performance metrics of a cooperative relay network using the DF protocol and the MRC approach at the destination, BER and power consumption were evaluated in Reference 14. In Reference 15, DF protocol was used to evaluate the average symbol error rate performance of wireless networks over uniformly distributed Rayleigh fading channels where the optimal relay selection technique has been used. The threshold and the co‐channel interference have a considerable impact on the system's BER execution, as shown in Reference 16 for a Dual‐hop DF Incremental Relaying (DF‐IR) system through Nakagami‐m fading channels with the presence of several L distinguishable interferers located near to the destination.…”

One of the promising technologies for achieving virtual diversity gains is cooperative relaying. This study considers a dual‐hop dual‐branch cooperative diversity system with an amplify‐and‐forward mechanism where the hop count here means the total number of relays between source and destination which equals two. Utilizing the best‐path selection combining technique, a closed‐form formula for the average bit error rate and outage probability is obtained. Furthermore, between the nodes in the two branches, we consider independent non‐identical Nakagami‐m slow flat fading channels. The Monte Carlo simulation results are confirmed with the analytical ones.

“…In (Molisch and Win, 2004;Sanayei and Nosratinia, 2004), the authors have simultaneously applied selection diversity to both the transmitter and receiver to conserve the advantages of the MIMO system and, at the same time, reduce the cost of utilizing multiple RF elements. The authors (Banu et al, 2022) have analyzed the ASER performance using MRC schemes with moment generating function (MGF) for QAM modulation over uniformly distributed Rayleigh fading channel by employing DF dual-hop relaying. Another challenging task in cooperative communication is to select the best relay for setting up the transmission, so the authors in (Clarke and Lamare, 2012) proposed various relay selection and minimum power allotment algorithms.…”

This study comprehensively assesses a decode-and-forward relaying system that employs Transmit Antenna Selection/Maximal Ratio Combining (TAS/MRC) for multi-hop communication across Fisher-Snedecor F fading channels. The study primarily focuses on the average symbol error rate (ASER) and outage probability (OP) while using cross QAM (XQAM) and rectangular quadrature amplitude modulation (RQAM). The proposed MIMO system effectively decreases the hardware complexity and cost of large antennas by implementing Transmit Antenna Selection (TAS) at the source and relay nodes and Maximum Ratio Combining (MRC) diversity at the destination and relays. Analytical formulations for OP (outage probability) and ASER (average symbol error rate) are derived using PDF (Probability Density Function)-based methods. Monte-Carlo simulations further validate these formulas. The investigation indicates that system performance is improved under conditions of lighter shadowing compared to moderate and extreme shadowing settings. Additionally, increasing the hop count amplifies the observed performance. Moreover, when the fading parameter increases, both the OP and ASER decrease. This study comprehensively examines the impact of many parameters, including m, p, L, R, and o, on the behaviour of the system under Fisher-Snedecor F fading. Based on the findings, the combination of shadowing and multipath fading significantly affects the system's performance, with both m and p significantly influencing this. When examining the Signal-to-Noise Ratio (SNR), a comparison between RQAM and XQAM demonstrates that XQAM is superior. The research uncovers crucial information for planning and executing the TAS/MRC-based MIMO multi-hop communication system. This technology possesses the capability to enhance the effectiveness of similar communication systems, as seen by the encouraging advancements in performance, especially in scenarios including signal attenuation.
