What is ISI in modulation?
Intersymbol interference (ISI) occurs when a pulse spreads out in such a way that it interferes with adjacent at the sample instant.
What is intersymbol interference in digital communication?
In telecommunication, intersymbol interference (ISI) is a form of distortion of a signal in which one symbol interferes with subsequent symbols. This is an unwanted phenomenon as the previous symbols have a similar effect as noise, thus making the communication less reliable.
What is the difference between aliasing and inter symbol interference ISI )?
Intersymbol interference is normally a linear, continuous-time phenomenon, while aliasing is associated strictly with sampled (quantized time) systems.
What is meant by intersymbol interference?
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.
