%% Cross-Correlation Between Two Signals and Reference Signal % Load a gong sound signal. First, use the gong signal as a reference signal. Then, % duplicate the signal twice, introducing time delays of 5 and 25 seconds. % Leave the sampling rate to its default of one hertz. Use |gccphat| to estimate the time % delays between the delayed signals and the reference signal. load gong; refsig = y; delay1 = 5; delay2 = 25; sig1 = delayseq(refsig,delay1); sig2 = delayseq(refsig,delay2); tau_est = gccphat([sig1,sig2],refsig)
