“…These effective services of NOMA scheme can revolutionize the performance of wireless communication networks in the future. However, the conventional power-domain PD-NOMA has already been implemented under the title of multi-user superposition transmission (MUST) in 3GPP release 13, but later omitted from 3GPP release 17, due to efficiency degradation of the wireless signal arising from channel estimation errors because it was using successive interference cancellation (SIC) at the receiver [39]. Also, the conventional NOMA scheme requires power-sharing among multiple NOMA users, which causes latency and degradation of signal-to-interference-plus-noise ratio (SINR) for each user [39] [40] [41].…”

Considering the advancements of the internet of things (IoT) in 6G and beyond communications, data transmission security in IoT devices has received extensive interest because of their significant features, such as low computational complexity, led by low power requirements. In such devices, the conventional cryptographic techniques may fail to provide secure communication. To fight this drawback, physical layer security (PLS) has remarkable potential to provide security solutions suitable for such applications. In this work, a highly effective PLS technique is proposed for providing secure communication against external and internal eavesdroppers in a downlink multi-cell, multi-user, and multicarrier IoT communication system. In our proposed system, we considered two base stations, where each base station uses a single radio frequency (RF) chain to link two antennas that are used for the transmission of data. Further, we transmit the data in two rounds, and each round of transmission occurs through a single active antenna of each base station. A different antenna is used for each round of transmission to communicate with two single antenna IoT devices/users in the presence of a passive eavesdropper. In the proposed algorithm, frequency selective channel-based pre-coder matrices and the dual transmission approach are jointly employed. The dual-transmission is performed simultaneously from two base stations to provide security against internal and external eavesdroppers. The proposed system is suitable for IoT-based applications. Also, the potential capabilities of our proposed algorithm are proved by extensive mathematical and simulation analysis.

The protection of digital content is increasingly becoming a significant issue for researchers and engineers. In this context, nonlinear dynamic systems play a vital role in information security through their chaotic behavior and susceptibility to initial conditions. This research presents a 3D chaotic map-based symmetric algorithm for multiple images to improve encryption efficiency and encourage secure transmission. The proposed scheme comprises the following four modules: the combination (the images are combined into a single image by merging their color channels); the permutation (using the suggested 3D chaotic map); the S-box generation; and the substitution through the AES substitution method. The proposed algorithm's encryption strength was determined through Entropy, Correlation coefficient, NPCR, and UACI analyses, which were then compared to the past techniques. Furthermore, the proposed method is assessed in terms of its computation time. Results demonstrate that it is highly efficient and secure for real-time communication.

“…In [25] the author analyzes the drawbacks in conventional NOMA and presents a new kind of NOMA with more improved performance metrics. Furthermore, in [26] the proposed model uses the wireless channel characteristics to eliminate user interference as well as completely degrade the received signal at the eavesdropper's terminal. Moreover, In [27] the new proposed NOMA systems are motivated by the many limitations faced by current NOMA-based systems.…”

Orthogonal Frequency Division Multiplexing with Subcarrier-Power Modulation (OFDM-SPM) has recently been proposed as a promising, potential transmission technique for future wireless communications (i.e., 6G and beyond) due to its multiple beneficial characteristics, including higher spectral efficiency, low latency with good reliability while maintaining low complexity. In this paper, the OFDM-SPM technique is compounded with Alamouti space-time block coding (STBC) in a multiple-input-single-output (MISO) set up to study, investigate and quantify the wireless system's performance of their combination over a multipath Rayleigh fading channel. Particularly, we analyze the two main performance metrics, bit-error-rate (BER) and throughput of the newly designed technique called OFDM-SPM-STBC, and then quantify the amount of gains in both BER and throughput. For making STBC work well with OFDM-SPM, a suitable equalizer is proposed for detecting the SPM power bits, and it is observed that there is a considerable improvement in the BER performance. We also consider two scenarios for OFDM-SPM-STBC transmission. The first one is the power reassignment policy (PRP), and the second one is the power saving policy (PSP). It is found that the sub-carrier optimized power-reassignment scheme provides the best BER performance for the proposed transmission scheme. In contrast, the PSP for SPM provided an intermediate improvement in an average BER.
