A Decision-Free Equalization Scheme for Minimum-Phase Channels

Research output: Contribution to journalArticlepeer-review


An algorithm previously used for estimating parameters of the vocal tract with a digital filter is here reexamined from the point of view of equalization theory. The procedure of adjusting equalizer taps to minimize the mean-squared sample values at the output of the equalizer (while keeping a particular equalizer tap fixed at unit value) is shown to result in an equalizer that inverts the channel provided that 1) the channel is minimum phase, and 2) the equalizer is one-sided.
