摘　　要：在通信数据传输过程中,受到复杂因素的影响,容易出现编码丢帧的现象,影响丢帧差错检测脉冲响应。基于此,笔者设计一种通信多码率自适应(Adaptive Multi-Rate,AMR)语音编码丢帧差错检测方法。首先,提取语音编码丢帧数据,初步检测语音编码丢帧差错数据;其次,进行丢帧差错数据矢量化处理,减少丢帧差错数据带来的负面效应;最后,计算ARM语音编码脉冲响应,进一步提高差错检测精度,进而实现通信ARM语音编码丢帧差错的精准检测。采用对比实验的方式,得出新方法的脉冲响应时间更加趋近于“1”的结论,验证了新方法的检测效果更佳,极具推广价值。In the process of communication data transmission,affected by complex factors,it is easy to encode the frame loss phenomenon,affecting the frame loss error detection pulse response.Based on this,the author designs an Adaptive Multi Rate(AMR)speech coding frame loss error detection method.Firstly,extract the voice coding frame loss data,initially detect the voice coding frame loss error data.Secondly,perform the frame loss error data vectorial processing,reduce the negative effects caused by the frame loss error data.Finally,calculate the ARM voice coding pulse response,further improve the error detection accuracy,and then realize the accurate detection of the communication ARM voice coding frame loss error.Using the comparative experiment method,the pulse response time of the new method is more likely The conclusion near“1”proves that the new method has a better detection effect and is of great promotion value.
