摘要

PROBLEM TO BE SOLVED: To reduce an encoding amount by achieving high encoding efficiency to signal strings. SOLUTION: The encoding device is a device for encoding the signal strings compressing amplitude, and includes a multi-stage linear prediction means. The encoding device performs reversible linear correspondence processing to input signal strings to make a close linear relationship with the signal strings before compression with at least any one linear prediction means. The encoding device obtains prediction coefficients by performing linear prediction to the signal strings subjected to linear correspondence processing. COPYRIGHT: (C)2009,JPO&INPIT
