The primary objective of this paper is to provide the requirements the network to equalize a signal and then send it without using demodulation or error-correction. Where the objective of the equalizer is to separate out the multiple paths and provide a clean, distortion free. This is one of the practical applications for adaptive processes for equalization.
Most communications systems have three processes at the receiver; equalization, demodulation and error-correction. The equalization process remove Inter-Symbol Interference (ISI) caused by the channel from a sequence of symbols. To compensate corruptions caused by ISI and to find the original information transmitted, equalization process performed at the receiver. Equalization refers to any signal processing techniques used at the receiver to combat ISI in depressive channels in the presence of additive. Equalizing filters must cancel out any group delay and phase delay between different frequency components.
