Conflicts emerge when the data transmission occurs between electrical equipment in an automobile. Hence, transmission delays appear as issues. For this reason, a method, called data transmission control, for electrical equipment of automobiles based on the 5G communication technology is proposed in this paper. Firstly, the wavelet feature decomposition was utilized to partition the frequency spectrum, and thus the statistical characteristics of electrical equipment of automobiles concerning the transmitted data were obtained. Then, the high-order approximate distribution method was adopted to construct a channel for a 5G network data transmission. Afterward, the control logic structure of the data transmission was built, and the problem, called the conflict of the data transmission, was alleviated through concurrent data collection and processing methods. On this basis, coding coefficients of a constructed global coding matrix were selected to encode and transmit source information. Also, the number of redundant data packets at each layer was adjusted. Finally, the data transmission control of the electrical equipment of the automobile was realized through the linear combination of the network nodes. The simulation results showed that the throughput of the proposed method was always higher than 7.7 MB/s, the bit error rate was around 0 when the signal-to-noise ratio was lower than 3, and the transmission delay was always below 0.5 s, which could provide a reference for the efficient and safe operation of automobiles.

Vehicle‐to‐vehicle communication can be effective in avoiding accident and traffic collision using dedicated short‐range communication (DSRC) in intelligent transportation systems. The problem of DSRC is it works in a short range of 1000 m and its frequency band cannot support a large number of users simultaneously, which leads to multiaccess interference, (MAI) noise, and low transmission rate. Multiaccess interference is referred as the overlapping of signals from different users in the network. A combination of the Worldwide Interoperability for Microwave Access (WiMAX) and the DSRC is proposed to improve the quality of service and network congestion using multiuser detection (MUD) and scheduling technique. This paper proposes a scheduling algorithm called league championship priority scheduling algorithm. In the league championship priority scheduling algorithm, the message will be sent on priority basis, depending on the bandwidth values and network coverage, so that MAI can be avoided. Moreover, MUD plays a major role in identifying the active users and nonactive users based on the condition of the threshold frequency and bandwidth. Thus, the implementation result shows that the proposed algorithm provides high‐transmission data rate and multiaccess interference can be avoided. The performance is evaluated to validate and estimate the performance of MUD and scheduling algorithm.
