为了满足数字通信及其它商业应用的需求,语音压缩编码技术得到了迅速发展。特别是低码率语音编码的研究具有十分重要的现实意义。在现有的语音编码研究中,混合激励线性预测编码(MELP)是一种比较好的方法。对MELP编解码算法的原理进行简要分析,讨论如何在MATLAB上实现该算法,并研究其关键技术,最后对测试结果进行分析和比较。
In order to meet the needs of digital communications and other commercial applications, voice compression coding technology has been rapidly developed. Especially the research of low bit rate speech coding has very important practical significance. In the existing speech coding research, mixed excitation linear predictive coding (MELP) is a better method. The principle of MELP coding and decoding algorithm is briefly analyzed. It is discussed how to implement the algorithm in MATLAB and to study its key technologies. Finally, the test results are analyzed and compared.
