Abstract :
This paper presents a new windowing scheme that effectively reduces the joint effect of intercarrier interference (ICI) resulting from frequency offset and additive noise in orthogonal frequency-division multiplexing. The transmitter does not need to be modified, subcarrier orthogonality in the receiver is preserved, and the receiver discrete Fourier transform size can be retained. The simulation results show that the new proposed window has a better performance than the common raised-cosine window, "better than" raised-cosine window and the maximally flat (MF) window
