Design of 5G Communication channel Transmission control System based on parallel interference cancellation
Abstract：In order to solve the connection timeout problem of 5G communication signal and enable it to present a relatively smooth transmission state in the case of single frame, multiple frame and continuous frame, a 5G communication channel transmission control system based on parallel interference cancellation is designed. The main power module and communication signal acquisition module are combined, and the output control structure and data processing structure are connected to the established control nodes of the power platform to complete the functional scheme design of the 5G communication channel transmission control system. On this basis, the signal transmission environment in the 5G communication channel is analyzed. By setting the parallel interference cancellation detector, the expression result of residual multiple access information is obtained, and the 5G communication channel configuration based on the parallel interference cancellation is completed. According to the interference variance calculation expression, determine the transmission error rate level of 5G communication signal, realize the analysis and research of system control instructions, combined with the structure of related hardware equipment, complete the design of 5G communication channel transmission control system based on parallel interference cancellation. The experimental results show that compared with the dynamic wireless control system, under the action of parallel interference cancellation algorithm, the connection duration of 5G communication signal can be better controlled in the case of single frame, multi-frame and continuous frame, which can play a certain promoting effect on the smooth transmission of signal parameters.
