MDCTQuantFwd

Performs split spherical vector quantization.

Syntax

IppStatus ippsMDCTQuantFwd_G7291_16s32u(const Ipp16s pMDCTCoeffs[320], const Ipp16s pBitsNumber[18], Ipp32u pDst[18]);

Parameters

pMDCTCoeffs	Pointer to the MDCT coefficients.
pBitsNumber	Pointer to the input number of bits allocated per subbands.
pDst	Pointer to the output vector quantization.

Description

The function ippsMDCTQuantFwd_G7291 is declared in the ippsc.h file. This function perform spherical vector quantization. This operation id divided into two steps: search for the best codevector and indexing of the selected codevector. See [ITU7291] section 6.6.9.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
