PERFORMANCE IMPROVEMENT OF OFDM SYSTEM BY USING ICI SELF CANCELLATION TECHNIQUE

Abstract

OFDM is the expected performance for 4th Generation broadband multimedia wireless systems. OFDM is robust to multi-paths fading and delay because it has high data transmission capability with high bandwidth efficiency that’s why it has recently been applied in wireless communication systems. the causes of loss of orthogonality and amplitude reduction of OFDM signal and lead to Inter Carrier Interference (ICI) is due to OFDM system is very sensitive to carrier frequency offset, which is one of the major drawback of OFDM system. We can reduce ICI by using various techniques. Here in this paper ICI self cancellation method is used to combat the effect of ICI induced by CFO
