Intelecommunication, intersymbol interference (ISI) is a form ofdistortion of a signal in which one symbol interferes with subsequentsymbols. This is an unwanted phenomenon as the previous symbols havesimilar effect as noise, thus making the communication less reliable.ISI is usually caused by multipath propagation or the inherentnon-linear frequency response of a channel causing successive symbols to'blur' together. The presence of ISI in the system introduces errors inthe decision device at the receiver output. Therefore, in the design ofthe transmitting and receiving filters, the objective is to minimize theeffects of ISI, and thereby deliver the digital data to its destinationwith the smallest error rate possible. Ways to fight intersymbolinterference include adaptive equalization and error correcting codes.…
