Classification: CPC G | IPC G

Claim 11:
12. The non-transitory computer-readable storage medium according to claim 11, wherein the parameter value, the energy spectrum, and the weighting factor satisfy the following relation:

wi=∥A(LSF(i))∥−p,

wherein
Wi represents the weighting factor;
A (⋅) represents the energy spectrum of the linear prediction filter;
LSF represents a vector of the original line spectral frequency parameter;
i represents an index of the vector, wherein 1≤i≤M, and M is a linear prediction order;
p represents the parameter value corresponding to an encoding mode of the to-be-encoded signal; and
∥⋅∥−p represents solving a 2-norm, which is of the vector, to a power of −p, wherein p is a number greater than 0 and less than 1.
