这里有fft,ifft,conj,xcorr,resample的用法。-Here are fft, ifft, conj, xcorr, resample usage.

周期信号加上白噪声，通过在matlab中，用XCORR函数，求出周期信号，干扰信号，和观测信号的自相关函数，三者互相进行比较-Periodic signal plus white noise in matlab by using XCORR function, the autocorrelation function of a periodic signal is obtained, the interference signal, and the observed signals, compa

我们现在可以互相关信号以模板T1和T2与xcorr功能，以确定是否存在匹配。-We can now cross-correlate signal S to templates T1 and T2 with the xcorr function to determine if there is a match.
