oWireless telecommunications requires high-speed access. One technique used to
overcome multipath fading is Ortoghonal Frequency Division Multiplexing (OFDM). The
weakness of OFDM occurs on the mobile channel due to time variations in the channel, giving
rise to intercarrier interference (ICI). The aim of the study is to determine the effect of
normalized carrier frequency offset on ICI and the effect of frequency selective fading tap
channel. The simulation results show the system performance in calculating the Eb / N0 5 dB
value that the greater the normalized carrier frequency offset (?), the worse the signal. The
simulation results show the OFDM-MIMO system performance in calculating the Eb / N0 5 dB
value that the greater the tap on the channel the worse the signal.vercome multipath fading is Ortoghonal Frequency Division Multiplexing (OFDM). The
