Introduction To Equalizers In most digital data transmission systems the dispersive linear channel encountered exhibits amplitude and phase distortion. As a result, the received signal is contaminatedby Intersymbo1 Interference (ISI). In a system, which transmits a sequenceof pulse-shaped information symbols, the time domain full response signalling pulses are smeared hostile dispersive by the channel, resulting in intersymbol interference. At the receiver, the linearly distorted signal has to be equalized in order torecover the information. The equalizers that are utilized to compensate for the IS1 can be classified according to their structure, the optimising criterion and the algorithms used to adapt the...
