LevinsonDurbin

Calculates LP coefficients from the autocorrelation coefficients.

Syntax

IppStatus ippsLevinsonDurbin_RTA_32f(const Ipp32f* pSrcAutoCorr, Ipp32f* pDstLPC, Ipp32f* pDstRC, int order);

Parameters

pSrcAutoCorr	Pointer to the autocorrelation vector.
pDstLPC	Pointer to the LPC output vector.
pDstRC	Pointer to the RC output vector.
order	Order of the LP filter.

Description

The function ippsLevinsonDurbin_RTA is declared in the ippsc.h file.

This function calculates linear prediction (LP) coefficients for the LP filter with the given order using the autocorrelation coefficients and Levinson-Durbin algorithm.

Return Values

ippStsNoErr	Indicates no error.
IppStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
IppStsRangeErr	Indicates an error when order is less than or equal to 0.
