5G Technology: Core Module Realization Scheme for faster data rate

Abstract

OFDM is one of the most common multi-carrier modulation schemes implemented for a range of wireless standards. The key drawback of the OFDM method is its frequency offset sensitivity, which contributes to loss of orthogonality. In OFDM system, when the orthogonality is lost ICI occurs which decreases the System Output. The reason for occurrence of Inter Carrier Interference because of the arising carrier frequency offset from the doppler shift from lesser extent. Various methods of Inter Carrier Interference cancellation techniques idea has also been discussed. In this project, the ICI triple cancelation scheme was proposed to minimize inter-carrier interference in a quick time varying environments. In this process, at transmitter section the Inter Carrier Interference self-cancellation modulation is observed and LTV model is modeled for time varying channel to perform ICI dual cancellation scheme and thus ICI self-cancellation demodulation is done at the end of the receiver.. The basic scheme is performed through channel estimation which works more efficient in fast varying systems The outputs obtained by this technique and by comparing MSE in various channel estimations demonstrates that the latest scheme is certainly better than the current scheme and increases the efficiency of the program.
