Survey Of Various Adaptive Equalizers For Wireless Communication And Its Applications
Abstract
A latest Digital Communication system incorporates short training time and has high tracking rate with an
application of channel equalizer. Various Equalization techniques provide balance for the time dispersion which is produced
by communication channels and conflict the generated inter-symbol interference (ISI) effect. If we are provided with a
channel of unknown impulse response, the main responsibility of an adaptive equalizer is to work on the channel output in
such a way that the cascade connection of the channel and the equalizer provides an approximation to an ideal transmission
medium. Generally, an initial training period is required by all the adaptive equalizers which are used in digital
communications during this training period the known sequence of data is transmitted. The same sequence is also made
available at the receiver terminal in proper synchronization with the transmitted data this makes it feasible for the filter to
adjust the coefficients in accordance with the adaptive filtering algorithm used in the equalizer design. We have provided
various methods that are incorporated in adaptive equalization techniques as an analysis in this paper.
