Examples
- Firstly , it introduces the development of speech coding , along with the significance of the low bit rate speech coding . it also compares the model of traditional dualistic excitation lpc vocoder and the multi - band excitation vocoder , and lucubrates the analytical method of frequency domain and time domain in the parameter extraction of multi - band excitation vocoding . secondly , based on the parameter extraction operation of keynote cycle , it adopts time domain in rough estimate operation of keynote and frequency domain in fine estimate operation of keynote , in according to the immediacy required in practice , to minish operation amount
本文阐述了一种基于fpga的多带激励语音编码器的研究与设计,首先介绍语音编码研究的发展状况以及低速率语音编码研究的意义,接着对比分析了传统二元激励lpc声码器模型和多带激励编码器模型,并深入研究了多带激励语音编码参数提取的频域和时域分析法,然后根据实际应用的实时性要求,为了减小运算量,在基音周期参数的提取的算法实现上,本文采用在时域进行基音粗估运算,在频域进行基音精细估计运算。 - 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。
