bicoherence (a third order moment) computing for a signal with MATLAB

Hi does anyone know how to compute bicoherence of a signal. I need it for nonlinearity check of the system that produce it. there are some MATLAB codes in the web for example in the:

http://www.nt.ntnu.no/users/skoge/diplom/diplom06/manum/Quantification/bicoherence.m

but I donot know how I should use them.

Thank you very much! Start a New Thread

Hello,

You can try out the Higher Order Statistical Analysis (HOSA) Toolbox developed by Ananthram Swami. Therein you can find a function named 'bicoher' to estimate the third order moment of a given signal.
