基于IP网络业务的增强交织帧丢失抑制方法
An Enhanced Interleaving Frame Loss Concealment Method for Voice Over IP Network Services
摘要：
本文以AMR WB G.722.2语音编解码器为研究对象，讨论了利用Word16（16 bit）对发送帧进行编码，从而充分利用语音编解码器的带宽资源。722.2语音编解码器的丢包隐藏（PLC）方法，以克服这一问题，提高解码语音质量的突发帧丢失条件下的帧交换网络的效率。客观和主观实验结果表明，我们提出的算法可以获得更好的语音质量。我们提出的方法实现了PESQ值高于2，在20%的帧删除率，并确保我们修改后的解码器和非修改的G.722.2编码器之间的兼容性。
英文摘要：
This paper focuses on AMR WB G.722.2 speech codec, and discusses the unused bandwidth resources of the senders by using a Word16(16 bit) to encode the sent frames. A packet loss concealment (PLC) method for G.722.2 speech codec is proposed in order to overcome this problem and increases the efficiency of this codec by improving the quality of decoded speech under burst frame loss conditions over frame-switched networks. Objective and subjective experimental results confirm that our proposed algorithm could achieve better speech quality. Our proposed method achieves a PESQ value higher than 2 at 20% frame erasure rate and ensure the compatibility between our modified decoder and the non-modified G.722.2 coder.
