Summary: This paper proposes an analytical framework based on a mixture gamma distribution for studying NOMA wireless systems over composite fading channels. The analysis includes the impact of imperfect successive interference cancellation on outage probability, delay-limited throughput, and effective capacity in uplink NOMA. The study also considers various fading channel models and provides closed-form expressions for performance metrics.

Summary: This paper studies a new DFCO-NOMA system where a secondary network shares the license spectrum of a primary network. Asymptotic expressions for the outage probability of both secondary and primary destinations, diversity order for primary and secondary symbols, and optimal power allocation coefficients are derived. The impact of various parameters on the outage performance is investigated and results are verified through Monte Carlo simulations.

Summary: This paper combines the NOMA and FD techniques in a downlink of wireless cooperative relay communication system to study the performance of V2V communication. The impact of self-interference, outage probability, and ergodic capacity is analyzed. The results show that the system performance decreases significantly due to self-interference, and the system reaches its performance limit in the high SNR region. Power allocation coefficients are determined based on the distance between vehicles, path loss exponent, and residual self-interference to achieve similar performance for both users. The optimal relay locations are also discussed.

Summary: This paper analyzes the secrecy attributes of a full-duplex relay (FDR) non-orthogonal multiple access (NOMA) system with partial relay selection (PRS) protocol. The expressions for exact secure outage probability (SOP), approximate SOP, and exact ergodic secrecy capacity (ESC) are derived, considering the impacts of outdated channel state information (CSI) at source and imperfect CSI at colluding eavesdroppers. Comparison with benchmark systems shows that the NOMA-FDR system has better secrecy performance.

Summary: This paper provides a unique procedure to evaluate the outage probability of downlink NOMA in future generation wireless networks. The derived expressions are precise by considering channel state information error, successive interference cancellation, and intra- and inter-cell interference. The outage probability is derived under various fading conditions, including homogeneous and non-homogeneous fading channels. Numerical results show the impact of different fading parameters, error in channel estimation, SIC, and number of interferers on the outage performance, and also analyze the effect of shadowing.

Summary: In this article, the impact of correlated fading on the performance of wireless multiple access channels (MAC) is investigated. The study considers the presence and absence of side information (SI) at transmitters, and models the fading coefficients according to the Fisher-Snedecor F distribution. The results show that the closed-form expressions of the outage probability (OP) and the average capacity (AC) can be derived under different system models and fading conditions, and are numerically validated.

Summary: This paper investigates the performance of a full-duplex relay system with multi-antennas, taking into account imperfect channel state information, transceiver hardware noise, and residual self-interference. Numerical results show a strong impact of these negative factors on the system's outage probability, symbol error rate, and ergodic capacity, especially at high data transmission rates and signal-to-noise ratios. Proper adjustments to source and relay transmission power are needed to achieve excellent performance and energy savings in the presence of these negative factors.

Summary: In this paper, the authors analyze the performance of an intelligent reflecting surface (IRS)-aided terahertz wireless communication system in the presence of pointing errors. They derive closed-form analytical expressions for the upper bounded ergodic capacity and approximate expression of the outage probability. The proposed analysis incorporates an alpha-mu fading channel model and considers both the IRS reflected channels and the direct communication channel.
