Carrier frequency offset, phase noise, timing offset and Doppler spread due to frequency error causes Inter Carrier Interference, which degrades the performance of Orthogonal Frequency Division Multiplexing (OFDM). In this paper, the authors present a comprehensive study of different types of Inter Carrier Interference (ICI) reduction technique, presented in different literature. They compare the performance of different methods by providing their CIR (Carrier to Interference Ratio) and BER (Bit Error Rate) graphs. The result shows that pulse shaping method is better than other methods.
