"WebSep 26, 2024 · This phenomenon is called inter-symbol interference (ISI). Dispersive effects are particularly relevant in high data rate communication systems. Delay dispersion can also manifest in time-variant multipath channels, since the copies of signals traveling via each propagating path may arrive at different times at the receiver thereby giving rise to ISI.
