  • Inter symbol interference is easily discarded by insertion of Cyclic Prefix at transmitter and removal of Cyclic Prefix at receiver.

  • Intra-symbol interference is not removed BUT suppressed in a way where frequency selective channel is converted into a transmission over N parallel flat-fading channels in the frequency domain.
