CODING METHOD AND DEVICE FOR LINEAR PREDICTION CODING PARAMETER

A linear prediction coding LPC parameter coding method is provided, to reduce redundancy of LPC parameter between channels, reduce a quantity of bits occupied for quantization coding on LPC parameters of multiple channels, and reduce calculation complexity of reference quantization coding on LPC parameters between channels while an amount of algorithm calculation is considered. The method includes: determining a reference LPC parameter from a plurality of LPC parameters, performing direct coding on the reference LPC parameter, and performing reference coding on a non-reference LPC parameter based on the determined LPC parameter.
