Impact of Inter- Carrier Interference in Wireless Communication

A Theoretical analysis of an OFDM wireless system considering the effect of inter-carrier interference (ICI) caused by Doppler frequency shift is carried out. The expression of the Signal to Noise plus ICI ratio (SNIR) and the Bit Error Rate (BER) for the OFDM system is derived. SNIR and BER for various system parameters are evaluated. Power penalty due to ICI in an OFDM wireless system is also evaluated.
