预测码 meaning in English
predictive code
Examples
- 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
同时,介绍tetra系统的市话网关,并在接下来的研究中详细介绍tetra电话网关中应用到的语音编解码算法? ?代数码本激励线性预测码( acelp )的基本原理,它是一种简化了的码本激励线性预测码( celp ) ,它把激励信号用代数码本代替,并且运用了均方误差最小、分析?合成等技术提取出语音的特征参数,极大地降低了比特率,而且具有较好的重建语音质量。 - To extent the use of this 1c , some circuit blocks are added . in the design , digital circuits are used to process the signal and control the precision of coding . and some circuits are used in different time by several functions to reduce the number of transistors used and the dissipation
电路设计中，为了便于信号处理以及控制编码精度，采用数字的方法进行量阶和预测码的计算；同时，为了减小电路规模，采用了时分复用的概念，用同一部分数字电路实现量阶调整和预测码的生成，增加了编码精度，减小了电路的规模和功耗。
