I need a MATLAB code for suppressing sidelobes in a signal using any of the windowing technique.Code should generate a random signal and do the windowing of sidelobes to suppress them.

There are many examples of this in the Signal Processing Toolbox documentation.

Just multiply the signal vector by your window of choice and then take the Fourier transform.

Enter

>>wintool

at the command line and you can explore the different sidelobe levels for various windows.

i want to analyse suppression on ofdm signal...so how do i insert the ofdm code in the wintool? so that i can observe the sidelobe suppression in ofdm using various windows??
