English abstract:
Modern cellular wireless systems would
not be possible without high-performance
equalizers. Signal impairments
introduced by the wireless channel can only be
compensated for by using such equalizers. This tutorial
serves as an introduction to the challenging
design of equalizers. By introducing a
general framework based on the
Bezout Theorem, we show
that the most sophisticated
equalizer concepts can be
derived, thus allowing
finite length solutions
to be found. Based on a
canonical receiver structure,
we also show how
equalizers improve the
Signal - to- Inter ference
and Noise Rat io (SINR)
under different sources of interference
such as temporal, spatial,
code and multiuser. We furthermore address the challenges
of adaptive equalizers as they are currently
typical solutions for low-cost devices. Although research
on equalizers has been performed for many
decades, we finish the tutorial with some open issues
that are still keeping the field alive.
