Residual echo signal in critically sampled subband acoustic echo cancellers based on IIR and FIR filter banks

Residual echo signal in critically sampled subband acoustic echo cancellers based on IIR and FIR filter banks

The residual echo signal characteristics of critically sampled subband acoustic echo cancellers are analyzed. For finite impulse response (FIR) filter banks, the residual echo signal usually has a relatively broad spectral nature around the subband edges. The residual echo signal of power symmetric...
