【摘要】：随着无线通信网络的快速发展,用户越来越重视通信网络的服务质量,而移动运营商为了满足用户对网络服务质量的要求,对网络质量的监控也在不断加强。语音质量评估系统正是在这种情况下快速的发展起来的。本文通过研究语音质量评价技术,在选中客观评价的基础上对其他早期语音客观评价模型PAMS、PSQM和MNB等进行了性能的分析,并通过对比发现这些早期的语音评价模型都有一定的缺陷,所适用的范围较小。基于此种原因,本论文选定了适用范围较广,语音质量评价较为稳定的PESQ算法模型,并对PESQ算法的实现原理进行了介绍。然后,根据PESQ算法对基于3G监控网络的PESQ算法进行设计与实现。通过对3G网络监控终端PESQ算法的功能的测试表明,本文所研究的基于3G网络监控终端PESQ算法其性能稳定,准确度较高,适合移动通信网络的实时监控,对及时优化网络质量具有一定的帮助。
[Abstract]:With the rapid development of wireless communication network, users pay more and more attention to the quality of service of the communication network. In order to meet the requirements of users, the monitoring of network quality has been strengthened. It is in this situation that the voice quality assessment system develops rapidly. Based on the research of speech quality evaluation technology, this paper analyzes the performance of other early objective speech evaluation models, such as PSQM and MNB. It is found that these early speech evaluation models have some defects and the scope of application is relatively small. For this reason, this paper selects the PESQ algorithm model which has a wide range of application and stable speech quality evaluation, and introduces the realization principle of PESQ algorithm. Then, according to the PESQ algorithm, the PESQ algorithm based on 3G monitoring network is designed and implemented. By testing the function of PESQ algorithm of 3G network monitoring terminal, it is shown that the PESQ algorithm based on 3G network monitoring terminal has stable performance and high accuracy, which is suitable for real-time monitoring of mobile communication network. It is helpful to optimize network quality in time.
