[Other] ICI_OFDM DL : 0: INTER-CARRIER INTERFERENCE CANCELLATION FOR OFDM SYSTEMS: Orthogonal Frequency Division Multiplexing (OFDM) is an emerging multi-carrier modulation scheme, which has been adopted for several wireless standards such as IEEE 802.11a and HiperLAN2. A well-known problem of OFDM is its sensitivity to frequency offset between the transmitted and received carrier frequencies. This frequency offset introduces inter-carrier interference (ICI) in the OFDM symbol. This project investigates three methods for combating the effects of ICI: ICI self-cancellation (SC), maximum likelihood (ML) estimation, and extended Kalman filter (EKF) method. These three methods are compared in terms of bit error rate performance, bandwidth efficiency, and computational complexity. Through simulations, it is shown that the three techniques are effective in mitigating the effects of ICI. For high values of the frequency offset and for higher order modulation schemes, the ML and EKF methods perform better than the SC method.

The first method is a self-cancellation scheme, in which redundant data is transmitted onto adjacent subcarriers such that the ICI between adjacent sub carriers cancels out at the receiver. The other technique the Extended Kalman Filter (EKF) method statistically estimate the frequency offset and correct the offset using the estimated value at the receiver-In a rapidly fading environment in high data rate wireless communication systems the orthogonality of OFDM sub carrier signals destroyed and this phenomenon potentially results in Inter carrier interference (ICI).The novel contribution of the paper is that, the effects of ICI have been analyzed and solutions to ICI diminution have been presented in different frequency offset values such as 0.5,0.15 and 0.30 .
