Description: 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. Platform: |

Description: Adaptive equalization教程-Adaptive equalizers compensate for signal distortion
attributed to intersymbol interference (ISI), which is
caused by multipath within time-dispersive channels.
Typically employed in high-speed communication
systems, which do not use differential modulation
schemes or frequency division multiplexing
The equalizer is the most expensive component of a data
demodulator and can consume over 80 of the total
computations needed to demodulate a given signal [01]

Description: Identification and Tracking of Rapidly Time Varying Mobile Channels for Improved Equalization.The goal of this paper is to
investigate the effectiveness of this channel tracking method when applied to rapidly fading channels. It is shown that, by appropriately
modifying the channel estimation and equalization procedures, the
same benefits as in a slow fading system can be obtained. Simulation results demonstrate the improved performance resulting from the use
of channel tracking in rapidly time varying channels. Platform: |
