基于飞坤内话语音信号比选技术的分析与研究

Analysis and Research of Voice Signal Comparison and Selection Technology Based on Frequentis Voice Communication Switching System

在民航地空通信中通过外接比选器或使用内话系统的比选功能来实现话音最佳信号选择有着非常重要的意义。阐述了基于快速傅里叶变换(FFT)的话音质量评估算法,分析和研究了飞坤内话在无线信号比选过程中的实现原理,对相关参数的设置方法进行了阐述。

In the civil aviation ground-air communication,it is very important to realize the best voice signal selection by connecting an external comparator or using the Best Signal Selection(BSS)function of the Frequentis Voice Communication Switching System(VCS).This paper expounds the voice quality evaluation algorithm based on Fast Fourier Transform(FFT),analyzes and studies the realization principle of Frequentis in the process of wireless best signal selection,and expounds the setting method of related parameters.
