摘要
A previously proposed IIR adaptive line enhancer (ALE) is explored further. We propose a mechanism for controlling the bandwidth of the ALE in an adaptive manner. The proposed mechanism increases the bandwidth of the ALE whenever its peak is not close to a spectral line of the input signal to assure its fast convergence and decreases the bandwidth of the ALE when its peak matches a spectral line of the input signal to enhance that spectral line further. In addition, a new algorithm for robust adaptation of the ALE is proposed.
