FIRLMSMRUpdateTaps

Syntax

Parameters

Description

The function ippsFIRLMSMRUpdateTaps is declared in the ipps.h file. This function updates the filter coefficients that are stored in the filter state structure pState. It is assumed that the filter operation was performed and the adaptation error value errVal was computed before calling this function. The adaptation error value is computed outside the function as the difference between output and reference signals. Updated filter coefficients are defined as h_n+1(i) = h_n(i) + mu * errVal * x(n- (i * dlyStep) - updateDly),

where h_n+1(i) denotes new taps, h_n(i) denotes initial taps, and mu, errVal and updateDly are the adaptation step, adaptation error value and adaptation delay, respectively. Before calling the function ippsFIRLMSMRUpdateTaps the filter state structure must be initialized by the function ippsFIRLMSMRInitAlloc.
