我们根据预测编码,在本文中描述了一种有效的话音信号编码方法。这种编码方法,发信和收信机均根据原先发射的信号,用线性预测来估计信号的电流值。把信号估算值和信号真值之差进行量化和编码,并发送到收信机。在收信机,译码的差别信 Based on predictive coding, we describe an efficient method of coding speech signals in this paper. This encoding method, sending and receiving machines are based on the original signal transmitted, using linear prediction to estimate the signal current value. The difference between the signal estimate and the signal true value is quantized and encoded and sent to the receiver. Differences in decoding at the receiver
