摘要
在标准的无线链路质量测试环境中测量手机终端的通话语音质量,可以评估手机终端耐受信道衰落的能力。针对这一应用需求,提出了一种无线通信通话语音质量测量试验装置,介绍了测量算法原理、装置组成以及测量方案,并在电磁混响室中应用该试验装置测试了手机终端的通话语音质量,为开展相关测试工作提供了参考。
The measurement results of cellphone speech quality in a standard wireless link test environment can be used to evaluate cellphone resistance in channel fading.In response to this demand,a speech quality measurement verification device for wireless communication is presented.The measuring algorithm principle,device composition,and measurement scheme are introduced,and the device is applied in the reverberation chamber to measure speech quality of cellphone.This study provides a reference for the development of related verification work.
