| Abstract | (OFDM) is considered as a digital multi carrier modulation technique. This technique will use a large number of closely spaced orthogonal subcarriers to avoid cross-talk. It provides high data rates with sufficient robustness to radio channel damages. A major problem in OFDM is carrier frequency offset error between the transmitted and received signals. Due to this the orthogonality of the subcarriers is no longer maintained which results in ICI (Inter carrier Interference). As a result the power leakage among the subcarriers which results in reduction in the system performance. In this paper, different ICI cancellation techniques such as frequency domain equalization, time domain windowing, pulse shaping and ICI self-cancellation are studied and our main concentration is on the ICI self-cancellation scheme. |
