摘　　要：针对传统误码监测方法未对通信节点分布情况进行分析,出现误码监测结果不佳及监测耗时长等问题,提出无线通信系统在线误码自动化监测方法。在相关工作分析的基础上,通过对通信系统进行前处理,结合处理所得通信数据,并将通信数据簇的发生情况近似看作一个泊松过程,构建复合型泊松模型,得出误码分布结果。以此为依据,引入CRC方法计算丢失码与反转码数量,求解得出通信系统误码率,完成无线通信系统在线误码自动监测。实验结果表明,所提方法的通信数据采集质量较高,误码监测结果与实际情况基本一致,且监测耗时最长不超过10s,性能优越,为无线通信相关领域的发展提供了参考依据。In allusion to the fact that the traditional BER monitoring method does not analyze the distribution of communi-cation nodes,which may bring about poor BER monitoring result and long monitoring time,the automatic online BER monitor-ing method for wireless communication system is designed.On the basis of the analysis of relatedwork,the communication sys-tem is pre-processed,the occurrence of communication data cluster is approximately regarded as a Poisson process,the com-pound Poisson model is constructed,and the distribution result of error code is obtained in combination with the obtained com-munication data.On this basis,the CRC method is brought in to calculate the number of lost codes and reversed codes,and the BER of communication system is solved to complete the online BER automatic monitoring of wireless communication system.The experimental results show that the method proposed in this paper has a high acquisition quality of communication data,the re-sult of error code monitoring is basically consistent with the actual situation,the monitoring time is not more than 10 s,and has a superior performance,which provides a reference for the development of wireless communication related fields.
