Abstract
Orthogonal frequency division multiplexing (OFDM) is a technology for high data rate broadband wireless communication system. It provides high spectral efficiency. The main limitation which degrades the performance of OFDM is inter-carrier interference (ICI), which is caused by Doppler frequency offset and transceiver local oscillator frequency offset. To mitigate ICI effect, a new method of ICI reduction using quadrature Kalman filter (QKF) is proposed and investigated. In this paper, we compared proposed method with pulse shaping and self-cancellation methods of ICI reduction for different digital modulation scheme. For simulation purpose AWGN channel is considered and results show that the proposed method outperforms the existing ICI reduction methods.
