Abstract:In order to improve the transmission stability of the 5G communication downlink channel and improve the control effect of the transmission control system, a 5G communication downlink channel transmission control system based on aggregation level is designed and developed. The DSP co-processor, the communication data collector and the channel transmission controller are modified to complete the optimization of the hardware system. According to the spatial structure and working principle of the channel, construct the communication downlink channel model and determine the real-time status of the communication downlink channel. Under this model, the real-time transmission data of the communication downlink channel is collected, and channel transmission resources are allocated according to the aggregation level of the channel. Finally, the transmission control function of the system is realized from the aspects of channel enhancement, sending/receiving end, transmission interference, and transmission speed. Through the system test experiment, it is concluded that the transmission rate control error, the channel transmission packet loss and the channel congestion probability of the designed system are reduced, that is, the designed system has more advantages in transmission control function.
