Abstract :
Results are reported which are of interest in the automatic equalization of telephone lines or other narrow bandwidth channels where data transmission is limited primarily by intersymbol interference. We describe an algorithm for adjusting the tap gains of a tapped delay line equalizer which converges for all channels. The algorithm also adjusts the tap gains to match a changing channel.
