Performs APCM inverse quantization.
Syntax
IppStatus ippsRPEQuantDecode_GSMFR_16s (const Ipp16s* pSrc, Ipp16s ampl, Ipp16s amplSfs, Ipp16s* pDst);
Parameters
pSrc |
Pointer to the input vector [13] of the RPE samples. |
ampl |
The block amplitude. |
amplSfs |
Scale factor of the block amplitude. |
pDst |
Pointer to the output reconstructed long-term residual vector [13]. |
Description
The function ippsRPEQuantDecode_GSMFR is declared in ippsc.h file. This function performs APCM inverse quantization of the input RPE samples. The output reconstructed long-term residual vector is formed as
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when one of the specified pointer is NULL. |
ippStsScaleRangeErr |
Indicates an error when amplSfs is less than 0. |
