algebraic coding technique
解釋
代數編碼技術-
Meanwhile, the telephone gateway in tetra system is introduced. in further research, the principle of tetra speech coding algorithm ? algebraic codebook excitation linear prediction ( acelp ) is introduced and analysed in detail, which is a advanced codebook excitation linear prediction ( celp ). acelp algorithm replaces the excitation signals with algebraic codebook and uses some technique such as minimizing the mean square error ( mse ) and the analysis - synthesis method to obtain characteristic parameters of speech
同時,介紹tetra系統的市話網關,並在接下來的研究中詳細介紹tetra電話網關中應用到的語音編解碼演算法? ?代數碼本激勵線性預測碼( acelp )的基本原理,它是一種簡化了的碼本激勵線性預測碼( celp ) ,它把激勵信號用代數碼本代替,並且運用了均方誤差最小、分析?合成等技術提取出語音的特徵參數,極大地降低了比特率,而且具有較好的重建語音質量。
