| 摘 要： | 介绍了煤矿井下语音通信系统的发展现状,指出了现行的语音通信系统具有编码算法复杂的缺点。将压缩感知理论引入到煤矿井下语音通信系统中,提出一种压缩感知编解码与传统编解码相混合的编解码方法。最后通过实验仿真了基于压缩感知的语音重构,从重构结果的MOS评分可以看出该算法降低了井下终端的编码复杂度,节约了终端的能耗,延长了其生存时间,基本与MP3的压缩效果相当。证明了该算法可以很好的应用于煤矿井下语音通信系统中。

| Abstract: | Development status of underground voice communication system was presented,and the disadvantage of a complex encoding algorithm in existing voice communication system pointed out.Compressed sensing theory was introduced into voice communication system in the study,and a mixed coding algorithm was proposed based on compressed sensing and traditional coding algorithm.Simulation of voice reconstruction based on compressed sensing was performed.From the MOS score of reconstructed voice,it＇s concluded that the algorithm reduces complexity of underground terminal encoding,saves terminal power consumption and prolong their survival time,which compresion effect is good as the same as MP3.The study results showed that the mixed algorithm is very comfortable for underground voice communication system in coal mines. |
