Abstract
Frequency offset introduces inter-carrier interference (ICI) in the OFDM symbol. We can investigate effective method for combating the effect of ICI. Through simulations, it is shown that for larger value of normalized frequency offset weight of the desired signal component decreases while weight of the ICI component increase. ICI self cancellation scheme gives more than 15 dB CIR improvement in the larger range of normalized frequency offset. Especially for small to medium frequency offsets range the CIR improvement can reach 17 dB.
