Description: Adaptive Filter. This script shows the BER performance of several types of equalizers in a static channel with a null in the passband. The script constructs and implements a linear equalizer object and a decision feedback equalizer (DFE) object. It also initializes and invokes a maximum likelihood sequence estimation (MLSE) equalizer. The MLSE equalizer is first invoked with perfect channel knowledge, then with a straightforward but imperfect channel estimation technique. Platform: |

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]
