How Does The Equalizer's Parameters, Channel Characteristics or Input Signal Constellation Affect The Equalization Performance?
Pp. 112-131 (20)
It is very important for a system designer to understand the connection between the
equalizer's performance (achievable residual intersymbol interference (ISI) and con-
vergence speed) and the various parameters involved in the equalizer's design such
as the equalizer's tap length, step-size parameter, channel power and input constel-
lation in order to achieve optimal and expected equalization performance. In this
chapter, we show the connection between the equalization performance (achievable
residual ISI and convergence speed) and the step-size parameter, equalizer's tap
length, channel power and input constellation statistics for type of equalizers where
the error that is fed into the adaptive mechanism which updates the equalizer's taps
can be expressed as a polynomial function of order three of the equalized output.
