In acoustic echo cancellation (AEC), frequency-domain adaptive filter (FDAF) algorithm is commonly used to improve the computational efficiency and the convergence rate. However, the choice of step size has to compromise between the convergence rate and the steady-state performance. A variable step-size algorithm was presented by Nitsch to tackle this(More)
This paper presents a new variable coefficients adaptive IIR notch filter for bass enchantment. The coefficients of the notch filter are controlled by an onset detector in order to obtain both fast convergence rate and low misadjustment. A single side-band (SSB) modulation is used to enhance the system robustness when the fundamental frequency is close to 0(More)
