Inter Symbol Interference, in telecommunication, is a form of distortion of signal in which one symbol interferes with other signals. As a result, noise is created and delivers a bad output.

The main reason for the ISI is: -

  • Multi-path Propagation
  • Non-linear frequency in channels

It is unwanted and it needs to be removed to get a good output. It is also important to know the cause of the ISI so that the effect of ISI can be reduced.
