|Title:||An IIR adaptive line enhancer with controlled bandwidth||Authors:||Farhang-Boroujeny, B.||Issue Date:||1997||Citation:||Farhang-Boroujeny, B. (1997). An IIR adaptive line enhancer with controlled bandwidth. IEEE Transactions on Signal Processing 45 (2) : 477-481. ScholarBank@NUS Repository.||Abstract:||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. © 1997 IEEE.||Source Title:||IEEE Transactions on Signal Processing||URI:||http://scholarbank.nus.edu.sg/handle/10635/61809||ISSN:||1053587X|
