Abstract

In this paper, the use of a new, real-time, perceptual speech quality metric for link adaptation in wireless systems, in general, and power control of global system for mobile communications (GSM), in particular, is investigated. It is shown that, due to better quality estimation of the new perceptual quality metric, efficiency of the link adaptation techniques is improved, thus saving precious system resources. In the example of GSM, for a given speech quality, the use of our perceptual speech quality metric in power control results in significant transmitter power savings (in excess of 2.5 dB) for moderate to high vehicular speeds as compared to when GSM's conventional link quality metric is used.
感知语音质量度量在无线系统链路自适应中的应用
本文研究了一种新的、实时的、感知的语音质量度量在无线系统中的链路自适应,特别是在全球移动通信系统(GSM)的功率控制中的应用。研究表明,由于新的感知质量度量具有更好的质量估计,提高了链路自适应技术的效率,从而节省了宝贵的系统资源。在GSM的例子中,对于给定的语音质量,与使用GSM的传统链路质量度量相比,在功率控制中使用我们的感知语音质量度量可以在中高车速下显著节省发射机功率(超过2.5 dB)。
