ICI Cancellation in OFDM Systems Under Stanford University Interim Channel Model
In orthogonal frequency division multiplexing (OFDM) systems, it is observed that intercarrier interference (ICI) is the most pervasive effect. Due to the Doppler shift or phase noise, the intercarrier interference effect will occur. In this paper, to alleviate the ICI, a parallel cancellation algorithm and space frequency techniques are combined to form a new technique called space frequency parallel cancellation scheme. The performance of this space frequency parallel cancellation approach is evaluated under SUI (Stanford University Interim) channeling environment.
