Implementation of ICI Self Cancellation in user's velocity from 0 to 700 Km/h to mitigate Inter-Carrier Interference

The effect of inter-carrier interference (ici) makes orthogonal frequency division multiplexing's (ofdm's) performance getting worst. ici itself can be caused by 2 causes,miss synchronization at transceiver and doppler phenomenon. but doppler phenomenon takes the highest responsibility for increasing the value of carrier frequency offset (cfo). doppler phenomenon is closely related to the movement or velocity of the user. the higher the velocity,the higher the value of cfo. in this paper,we evaluate ici self cancellation method to reduce the impact of ici while the increasing of the user's velocity. the simulation results show that the application of ici self cancellation in iterated velocity from 0 to 700 km/h gives ber's correction.
