ABSTRACT
Due to the distortive character of the propagation environment, transmitted data symbols will spread out in time and will interfere with each other, a phenomenon called intersymbol interference (ISI). The degree of ISI depends on the data rate: the higher the data rate, the more ISI is introduced. On the other hand, changes in the propagation environment, e.g., due to mobility in wireless communications, introduce channel time variation, which could be very harmful. Mitigating these fading channel effects, also referred to as channel equalization, constitutes a major challenge in current and future communication systems.
