Document Type and Number:
WIPO Patent Application WO/2012/008330
Kind Code:
A1
Abstract:
A correspondence table memory unit (22) stores a correspondence table that denotes the correspondence between an index that denotes the combination of the gain of a periodicity component and the gain of a pulse component, and a transformed index. A sorting unit (21) queries the correspondence table of the correspondence table memory unit (22) and acquires the transformed indices that correspond to the indices of the immediately preceding subframe and the current subframe. A difference calculation unit (23) calculates the difference between the transformed index of the immediately preceding subframe and the transformed index of the present subframe. A variable-length coding unit (24) codes the difference value and generates a variable-length code with a variable-length coding method that allocates a code that gets shorter as the absolute value of the value decreases.
