“…The related content of the model output control is obtained by summarizing the output results in order to further explain the model definition and stability in wireless communication networks [19,20]. By adopting this theory, the corresponding systematic changes can be calculated [21,22]. In order to further explain the upper limit characteristics of the data and calculations in the system, the model output extreme values shown in Figure 6 were obtained through analysis.…”

College students’ physical training is an important aspect of their studies and lives. In light of the existing issues with the accuracy of the physical training evaluation index for college students and other issues. Based on the theory of wireless communication networks, model definition and stability analysis methods are used to optimize the original model. The optimization model of a wireless communication network is obtained by considering the data output control theory, trained by college students. This model can analyze the big data of college students’ physical training and construct the corresponding data platform. Through calculations, the rules for data changes under different indicators can be obtained. Finally, the accuracy of the optimized model is verified by comparing it with the original model. Related studies show that the variable parameters in the control system include model parameters, network upper limit, and corresponding control system parameters. On the whole, the model parameters exhibit a consistent trend of change, while the upper limit of the network displays a characteristic three-stage linear pattern. The control system first increases rapidly and then exhibits a gradual decline in exponential function type. The control system and the switching system can be switched using model calculations. The two different change curves exhibit obvious symmetry characteristics when influenced by the output times. It shows that the two change systems have opposite effects on the model, and the overall volatility is relatively high. The wireless communication network model can analyze and build a platform for collecting college students’ sports training data. According to the model calculation, it can be seen that the changes in different indexes exhibit clear linear characteristics. Among them, the concepts of sports, personalized training, and basic training show linearly increasing changes. However, the training structure and content exhibit a typical linear decline. Finally, the advantages of the wireless communication network model are illustrated with the experimental data. This study can provide guidance and ideas for the construction of a data platform for college students’ physical training.

“…Another technology is non-orthogonal multiple access (NOMA), which allows multiple users to share the same time-frequency resources and can improve spectral efficiency and coverage. The performance analysis of MCM-NOMA in vehicular systems has motivated numerous studies, including a proposal for novel precoding method to reduce peakto-average power ratios [3], rate analysis [4]- [7], resource allocation optimization [6]- [8], and bit error rate analysis [9]- [11] among others. However, to the best of our knowledge, there has been no prior research that has analyzed the performance of MCM-NOMA systems in terms of sum rate and derived a closed-form expression for the rate of information transfer.…”

<p>This letter addresses the challenge of determining the maximum sum rate achievable in high mobility scenarios with time and frequency selectivity in 5G V2X communications, particularly in the context of IoT/sensor networks. We derive a closed-form expression for the maximum sum rate of a multicarrier non-orthogonal multiple access (NOMA) system with 𝑛 users, and validate our theoretical results through simulations by comparing them with traditional orthogonal schemes. Our work provides valuable insights into the potential of NOMA for high-speed V2X communications, and offers a novel contribution to the existing literature by presenting a closed-form expression allowing the development of efficient and reliable 5G V2X systems.</p>

Recent gains in the pervasiveness of Visible Light Communication due to its ability to simultaneously provide lighting and communication solutions make it the best candidate for enabling smart city infrastructure to have seamless connectivity. The fundamental challenge of this technology is to ensure high data rate communication while meeting the lighting requirements of smart cities. This work is focused on providing high data rate capacity using visible light communication. To realize this, diffused channel modeling and channel modeling are considered. A total of six channels, each carrying 10 Gbps data are multiplexed using polarization division multiplexing and wavelength division multiplexing transmitted over a diffused channel of 1.3 m, while the ranges of 8 m under clear conditions and 5 m under heavy attenuation are reported with modeling. The reported results show the successful transmission of data in terms of bit error rate and eye diagram.
