ESPRIT algorithm for wide-band signals

I've try ESPRIT algorithm with narrowband signal but with wide-band signal i am very confuse. I think there are 2 ways to apply ESPRIT algorithm for wide-band signal. first, You divided wide-band signals to many bins and then apply ESPRIT for each bins. I can simulate TLS-ESPRIT but i can't understand how to divide to many bins so i can't simulated it. second, apply extended ESPRTIT.
So, if you have code matlab or how to decompose wideband signal to narrow-band, then tell. I am very grateful if you help me.
