The paper compares ADPCM schemes using neural net-based nonlinear prediction against classical linear prediction methods, examining variations in adaptive quantization bits and adaptation types.
In this paper we compare several ADPCM schemes with nonlinear prediction based on neural nets with the classical ADPCM schemes based on several linear prediction schemes. Main studied variations of the ADPCM scheme with adaptive quantization (2 to 5 bits) are: -forward vs backward -sample adaptive vs block adaptive
