| 摘 要： | 对话音质量的评断往往非常主观，而“用户平均评价记分（ＭＯＳ）”方法则能提供一个较为客观的评价，休斯网络系统（ＨＮＳ）的ＧＭＨ２０００固定蜂窝系统获得了极高的ＭＯＳ，这意味着该系统提供的话音品质很高。本文介绍了影响固定蜂窝系统话音质量的一些关键因素，对模拟和数字数字蜂窝系统的ＭＯＳ评价作了比较，最后简述了ＧＭＨ２０００高话音品质的原因。

| Abstract: | Speech quality is usually subjectively evaluated, The Mean Opinion Score (MOS) method provides a fairly objective evaluation. HNS's GMH2000 fixed cellular system has got an extremely high MOS value. This means this system provides very high speech quality. This paper presents some key issues con-cernirrg fixed cellular speech quality and compares the MOS values of analog and digital cellular systems. Finally, it briefly describes the reasons for GMH2000's high speech quality. |
