【摘要】 以一种自适应预测编码器的设计为研究对象，重点描述了准周期预测器和数学模型及在计算机上的模拟，在分析模拟结果的同时指出采用自适应预测编码的方法能够构成数码率为１８００比特或稍低一点的语言数码化设备。在实际通话条件下可得到中等程度的语音质量。更多还原

【Abstract】 Taking the designing of a self- adapting predicting coder as the object,the paper describes the quas～cycle predictor mathematical model. The resnlt of analvsis indicates that by applying the self- adapting predicting coding,a language digit- ceded equipment,whose digit-code ratio is 4800 bps or a bit lower,ean be formed。In practial communications,a medium-level quality of speech sounds could bo1 achiev ed。更多还原
