Sidelobe suppression using Windowing

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.

Answer 1

[Wayne King]

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.

Answer 2

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??
