摘要
5G通信使用的是毫米波频段,相比于低频段而言,信号在传播中更容易受到信道干扰及多路径衰落的影响,导致5G通信信道拥塞概率与数据丢失概率较高,为此,设计并开发了基于云计算的5G通信信道传输控制系统;改装通信信道数据采集器、处理器、交换机合路器、均衡器以及控制器等元件,将其接入到系统电路中,实现系统硬件的优化;利用采集器设备,以动态方式采集5G通信信道传输数据,从时域和频域两个方面提取信道传输特征,综合特征匹配度和信道占用率两个方面,判断当前通信信道的运行状态;针对处于拥塞状态的信道,在传输控制协议的约束下,利用云计算技术实现5G通信信道传输任务的调度,最终通过通信信道增强、干扰消除两个步骤,实现系统的5G通信信道传输控制功能;实验结果表明,有干扰场景下,所设计系统的信道传输平均误码率为0.22%,信道传输数据丢包率的平均值为0.48%,5G通信信道的平均数据传输速度为406 GB/min。
5G communication technology uses millimeter wave frequency band,and compared to low frequency band,5G signals are more susceptible to channel interference and multi path fading during propagation,resulting in a higher probability of congestion and data loss in the 5G communication channel.Therefore,a 5G communication channel transmission control system based on cloud computing is designed and developed.Modify the communication channel data collector,processor,switch combiner,equalizer,and controller,and integrate them into the system circuit to achieve the optimization of the hardware system.Use the collector equipment,dynamically collect the 5G communication channel transmission data,extract the channel transmission features from both time-domain and frequency-domain aspects,and comprehensively evaluate the current operating status of the communication channel based on the feature matching degree and channel occupancy rate.For the congested channels,cloud computing technology is used to schedule the 5G communication channel transmission task under the constraints of transmission control protocols.Finally,the system s 5G communication channel transmission control function is achieved through two steps:communication channel enhancement and interference elimination.Experimental results show that under the interference scenarios,the average bit error rate of the designed system s channel transmission is 0.22%,the average data packet loss rate of the channel transmission is 0.48%,and the average data transmission speed of the 5G communication channel is 406 GB/min.
