On the basis of designing the serial structure of mq encoder, parallel structure of mq encoder is designed using pipelining technique and the coding rate is approximately 1bit / cycle
為了得到更高速率的mq編碼器，採用流水線結構設計了并行的mq編碼器。模擬結果表明mq編碼器的編碼吞吐量明顯提高，達到了硬體規模和編碼效率的平衡。 -
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
本文闡述了一種基於fpga的多帶激勵語音編碼器的研究與設計，首先介紹語音編碼研究的發展狀況以及低速率語音編碼研究的意義，接著對比分析了傳統二元激勵lpc聲碼器模型和多帶激勵編碼器模型，並深入研究了多帶激勵語音編碼參數提取的頻域和時域分析法，然後根據實際應用的實時性要求，為了減小運算量，在基音周期參數的提取的演算法實現上，本文採用在時域進行基音粗估運算，在頻域進行基音精細估計運算。 -
In the second part of this work, according to cosine function ' s cycle property and using the quantization square choosed by international standards such as jpeg, h261 / h263, mpeg1 / 2, a kind of dct coding algorithm that based on tabling is put forward
第二部分採用jpeg 、 h261 h263 、 mpeg1 2等國際標準中所選擇的量化矩陣，根據餘弦函數的周期性提出一種基於查表的dct編碼演算法。 -
