Embedded fuzzy control for automatic channel equalization after digital transmissions

A straightforward technique for automatic adaptation of channel equalizers after digital data transmission is presented. Inter-Symbol Interference (ISI) at the received signal is identified by scanning the input stream over time at the data clock frequency. The resulting 2D-figure is compared agains...
