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.
