Neuro-Fuzzy Equalizers for Mobile Cellular Channels

 

Preface

 

The purpose of a communication system is to transfer information between two separate points over some medium in the presence of disturbances or distortions such as noise and dispersion. This distortion is manifested in the time domain as pulse dispersion and is labeled as Inter-Symbol Interference (ISI). As data rates increase in modern digital communication systems, ISI becomes an inevitable consequence of the dispersive nature of band-limited propagation channels. The receiver must include an equalizer to mitigate the effects of ISI. Thus, an equalizer undoes the distortion that the signal is subjected to while it propagates through the channel. Needless to say, equalizers are present in all forms of communication systems: from ...
