wigner distribution

Hi, i need the time-frequency analysis of a signal, for that i need to go for wigner distribution. Can anyone please tell me how to perform wigner distribution of a signal.

Hi Sravantej,

Please see

http://tftb.nongnu.org/

The time-frequency toolbox by Professor Flandrin includes utilities for the Wigner distribution.

Hi wayne,

Thanks for the link, i got the time frequency wigner distribution.Now i need time frequency cross correlation between two wigner distributions, so that i can find the mutiple delays between those two signals. Could you please help me in doing so.

Thanks,

sravan
