What causes inter symbol interference?
ISI is usually caused by multipath propagation or the inherent linear or non-linear frequency response of a communication channel causing successive symbols to blur together. The presence of ISI in the system introduces errors in the decision device at the receiver output.
What is intersymbol interference in optical fiber?
Note 1: In fiber optic systems, intersymbol interference can occur when dispersion causes an excessive increase in pulse duration, i.e., spreading in time and space occupied by the pulse as it propagates along the optical fiber resulting in pulse overlap that might be so large that a photo-detector can no longer ...
How does intersymbol interference ISI arise in bandlimited digital signals and what is its effect on a system performance?
Inter Symbol Interference (ISI) dominantly causes huge data loss. It is caused due to multipath propagation, band-limited channels noise. Equalization, a process of inducing inverse channel response to compensate the effects of ISI is used to combat these effects.
What is ISI in communication?
Intersymbol interference (ISI) is a phenomenon in which the energy of a symbol spills over into succeeding symbols causing interference. Tight filtering at the transmitter and receiver and/or channel distortion can cause the waveform that represents a symbol to spread out into succeeding symbol periods.
