语音编解码算法 meaning in English
voice coding/decoding algorithms
Examples
- In communicaton the bandwidth is an important problem that we should consider , specially in wireless communication . in fact the fiber is mainly used in backbone networks , so it is essential to develop the low rating coding technology of voice . the arithmetic of melp is based on the model of lpc and use the form of mixed excitation . because it integrates the idea of multi - band , so it has the merit of lpc and mbe . it is a perfect coding scheme in low rating voice coding relatively
而melp语音压缩编码算法是在线性预测编码参数模型的基础上，采用混合激励的形式，并且结合了多带的思想，因此它拥有线性预测编码和多带激励的优点，是目前低速率语音编码中一种比较理想的编码方案，也是本文研究的重点。本论文通过研究melp的语音编解码算法的原理，对它的编解码过程作了比较深入的研究，对其中的一些公式进行了理论推导，并作了仿真分析，最后研究了该算法的c语言实现。
