Detailed Description

Instance structure for the Q15 normalized LMS filter.

Field Documentation

pCoeffs

q15_t* tpt_lms_norm_q15_s::pCoeffs

points to the coefficient array. The array is of length uTaps.

pShift

uint8_t tpt_lms_norm_q15_s::pShift

bit shift applied to coefficients.

pState

q15_t* tpt_lms_norm_q15_s::pState

points to the state variable array. The array is of length uTaps + aCount - 1.

qEnergy

q15_t tpt_lms_norm_q15_s::qEnergy

saves previous frame energy.

qMu

q15_t tpt_lms_norm_q15_s::qMu

step aCount that control filter coefficient updates.

qX0

q15_t tpt_lms_norm_q15_s::qX0

saves previous input sample.

uTaps

uint16_t tpt_lms_norm_q15_s::uTaps

number of coefficients in the filter.
