Abstract :
In Orthogonal Frequency Division Multiplexing (OFDM) carriers among users are orthogonally related. Hence no guard band is necessary like Frequency Division Multiplexing even spectrums of users can overlap, enhances the spectrum efficiency of the network. In this paper different window functions in frequency domain are considered in pulse shaping of OFDM data symbols which are considered uncorrelated. Under above considerations inter carrier interference (ICI) power becomes simply the square magnitude of window function. Here five different window functions are used for comparing performance of the wireless links in content of ICI power and desired received signal.
