Abstract:

At present， the phenomenon of network densification accelerates the degradation of channel transmission performance. And the widely used evaluation methods face significant challenges in evaluating channel transmission performance due to their limited consideration of parameters and constrained applicability. In response to the difficulties in evaluating channel transmission performance， a method for evaluating multi-parameter channel transmission performance through an improved Transmission Control Protocol/Internet Protocol （TCP/IP） frame structure was proposed. Firstly， the standardized test data was generated， including pseudo-random codes， basic curve data， and custom curve data， so as to ensure that the test data follow a uniform standard. Secondly， an improved TCP/IP frame structure was employed to package test data information， including total frame quantity and frame sequences， into the TCP/IP frames. In this way， the sending， receiving and parsing of test data were realized， and the statistics on basic channel transmission variables were completed， such as the number of frames by type， the number of frames by length， the total number of frames， and the volume of effective data. Finally， the received data were analyzed to obtain two types of high-level channel transmission information， namely frame error rate and bit error rate， completing the overall evaluation of the channel transmission performance. The designed method employed six parameters to evaluate channel quality， with the evaluation precision of the method reaching 0.01% and maintaining a minimum error margin of 0.01%. It is compatible with all communication channels using TCP/IP. Experimental results demonstrate that the proposed channel transmission performance evaluation method can perform the statistics and analysis of the six channel communication information， and evaluating the channel transmission performance accurately.

摘要：

目前，网络密集化现象加剧了信道传输性能的恶化。而普遍应用的评估方法由于参数考虑有限和适用范围受限，在信道传输性能评估方面面临显著挑战。针对信道传输性能评估困难的问题，提出一种改进传输控制协议/网际协议（TCP/IP）帧结构的多参数信道传输性能评估方法。首先，生成标准化的测试数据，包括伪随机码、基本曲线数据、自定义曲线数据，以确保测试数据遵循统一标准；其次，使用改进的TCP/IP帧结构，将总帧数、帧序号等测试数据信息封装在TCP/IP帧中，并对测试数据进行收发与解析，统计不同帧类型的帧数量、不同帧长度的帧数量、总帧数和有效数据量这4种基础信道传输信息；最后，分析接收数据得到误帧率和误码率这2种高级信道传输信息，完成信道传输性能的整体评估。所设计的方法采用6种不同的参数对信道质量进行评估，方法评估的精度可达0.01%，最小误差为0.01%，且兼容所有使用TCP/IP进行通信的信道。实验结果表明，所提出的信道传输性能评估方法可以完成对6种信道通信信息的统计与分析，准确评估信道传输性能。
