FixedCodebookDecode

Decodes the fixed codebook vector.

Syntax

IppStatus ippsFixedCodebookDecode_GSMAMR_16s(const Ipp16s* pSrcFixedIndex, Ipp16s* pDstFixedVector, Ipp16s subFrame, IppSpchBitRate mode);

Parameters

pSrcFixedIndex	Pointer to the fixed codebook index vector. If the mode is 12.2 kbps, the vector length is 10; if the mode is 10.2 kbps, the vector length is 7; otherwise the vector length is 2.
pDstFixedVector	Pointer to the 40-element fixed codebook vector.
subFrame	Subframe index.
mode	Bit rate specifier. Values between IPP_SPCHBR_4750 and IPP_SPCHBR_12200 are valid.

Description

The function ippsFixedCodebookDecode_GSMAMR is declared in ippsc.h file. This function decodes the fixed codebook vector from the received fixed codebook index.

Return Values

ippStsNoErr	Indicates no error.
IppStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsRangeErr	Indicates an error when mode is not a valid element of the enumerated type IppSpchBitRate.
ippStsSizeErr	Indicates an error when subFrame is not in the range [0, 3].
