ABSTRACT:
A method and apparatus for improving the quality of a signal which has been detrimentally affected by inter-symbol interference due to time dispersion. The invention includes selecting one of at least two algorithms of equalization and after the selection, and processing the signal by performing steps according to the selected algorithm.
