In this paper the reduction of Intersymbol Interference

(1 ) in mobile communication channels is addressed. A

well known technique for IS1 reduction is adaptive equalization

in which the time-varying characteristics of the mobile

channel is tracked by an adaptive algorithm. We compare

different adaptive strategies and equalizer structures with

respect to overall system performance in terms of computational

complexity, numerical stability, finite wordlength

effects, size and power consumption required for VLSI implementation.
