LevinsonDurbin

Calculates the LP coefficients using the Levinson-Durbin algorithm.

Syntax

IppStatus ippsLevinsonDurbin_GSMAMR_32s16s (const Ipp32s* pSrcAutoCorr, Ipp16s* pSrcDstLpc);

Parameters

pSrcAutoCorr	Pointer to the autocorrelation coefficients, a vector of length 11.
pSrcDstLpc	Pointer to the LP coefficients associated with the previous frame, a vector of length 11, represented using Q3.12. On output, updated to point to the LP coefficients associated with the current frame, a vector of length 11, represented using Q3.12.

Description

The function ippsLevinsonDurbin_GSMAMR is declared in ippsc.h file. This function calculates the 10th-order LP coefficients from the autocorrelation lags using the Levinson-Durbin algorithm.

Return Values

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