We analyze the effects of Doppler spread in mobile channels on Orthogonal Frequency Division Multiplex (OFDM) systems. This is important, since channel variations during one OFDM s...
—In this paper, we present an iterative algorithm for channel complex gains estimation with inter-sub-carrierinterference (ICI) reduction in orthogonal-frequency-divisionmultiple...
Orthogonal frequency division multiplexing based wireless systems are spectrally efficient, but they are vulnerable to inter carrier interference (ICI). In a wide area scenario, us...
