adaptive predictive coding (APC)

Adaptive Predictive Coding (APC) is a transformation technique used in narrowband A/D converters

. APC coding is a prediction method in which each sample is immediately predicted. The prediction is based on linear interpolation of the previous samples. The APV method is similar to Linear Predictive Coding (LPC) in that both methods use linear prediction. The difference between the two methods is that APC coding uses fewer prediction coefficients and therefore provides a higher sampling rate than LPC coding.
